Lazy Evaluation / Delayed Execution + +#### Pattern Description +Object construction and configuration are separate from data processing. + +#### Why This Pattern? +- **Validation Before Execution**: Catch errors before expensive operations +- **Inspection**: Users can examine table structure before building +- **Flexibility**: Modify configuration after initial construction +- **Performance**: Don't process data until explicitly requested + +#### Implementation in Tplyr + +```r +# Construction phase - no data processing +tab <- tplyr_table(adsl, TRT01P) %>% + add_layer( + group_count(RACE) %>% + set_format_strings(f_str('xx (xx.x%)', n, pct)) + ) + +# Inspection phase - examine structure +print(tab) # Shows configuration, not results + +# Execution phase - explicit trigger +results <- build(tab) +``` + +#### Key Characteristics +- `tplyr_table()` and layer constructors don't process data +- Configuration functions return modified object +- `build()` is the explicit execution trigger +- Environments store configuration until build time + +#### Refactoring Considerations +- Never process data in constructors or setters +- Keep `build()` as the single execution entry point +- Maintain clear separation between configuration and execution +- Test that construction is fast (< 1ms) + +### 3. S3 Method Dispatch for Polymorphism + +#### Pattern Description +Different layer types have different processing logic, implemented via S3 generics. + +#### Why This Pattern? +- **Extensibility**: Easy to add new layer types +- **Separation of Concerns**: Each layer type has its own implementation +- **R Idioms**: Follows R's object system conventions + +#### Implementation in Tplyr + +```r +# Generic functions +process_summaries <- function(x, ...) { + UseMethod("process_summaries") +} + +process_formatting <- function(x, ...) { + UseMethod("process_formatting") +} + +process_metadata <- function(x, ...) { + UseMethod("process_metadata") +} + +# Implementations for each layer type +process_summaries.count_layer <- function(x, ...) { + # Count-specific logic +} + +process_summaries.desc_layer <- function(x, ...) { + # Desc-specific logic +} + +process_summaries.shift_layer <- function(x, ...) { + # Shift-specific logic (reuses count logic) +} +``` + +#### Key Characteristics +- Three main generics: `process_summaries`, `process_formatting`, `process_metadata` +- Each layer type has its own methods +- Shift layers inherit from count layers +- Consistent interface across layer types + +#### Refactoring Considerations +- Maintain S3 method signatures +- Don't break dispatch by changing class names +- Test all implementations of a generic +- Consider inheritance (shift extends count) + +### 4. Quosure-Based Non-Standard Evaluation + +#### Pattern Description +User inputs are captured as quosures for delayed evaluation in data context. + +#### Why This Pattern? +- **Tidy Evaluation**: Supports both quoted and unquoted inputs +- **Context Preservation**: Captures both expression and environment +- **Flexibility**: Enables NSE in user-facing API while maintaining programmatic use + +#### Implementation in Tplyr + +```r +# Capture user input as quosure +tplyr_table <- function(target, treat_var, where = TRUE, cols = vars()) { + target_name <- enexpr(target) + new_tplyr_table(target, enquo(treat_var), enquo(where), enquos(cols), target_name) +} + +# Later evaluation in data context +treat_var_name <- as_name(treat_var) # Convert to string +treat_values <- eval_tidy(treat_var, data = target) # Evaluate in data +``` + +#### Key Characteristics +- `enquo()` captures single variable +- `enquos()` captures multiple variables (from `vars()`) +- `as_name()` converts quosure to string +- `eval_tidy()` evaluates in data context +- Supports both `TRT01P` and `"TRT01P"` inputs + +#### Refactoring Considerations +- Don't evaluate quosures too early +- Use `as_name()` for variable names, `eval_tidy()` for values +- Test with both quoted and unquoted inputs +- Understand quosure environment capture + +### 5. Builder Pattern with Fluent Interface + +#### Pattern Description +Objects are constructed through chained method calls. + +#### Why This Pattern? +- **Readability**: Code reads like a specification +- **Discoverability**: IDE autocomplete helps users +- **Flexibility**: Easy to add/remove configuration steps + +#### Implementation in Tplyr + +```r +# Fluent interface - each function returns modified object +tplyr_table(adsl, TRT01P) %>% + add_total_group() %>% + add_layer( + group_count(RACE) %>% + set_format_strings(f_str('xx (xx.x%)', n, pct)) %>% + add_total_row() %>% + set_order_count_method('bycount') + ) %>% + add_layer( + group_desc(AGE) %>% + set_format_strings( + 'Mean (SD)' = f_str('xx.x (xx.xx)', mean, sd) + ) + ) %>% + build() +``` + +#### Key Characteristics +- All configuration functions return modified object +- Supports `%>%` piping +- Declarative style +- Order of operations matters for some functions + +#### Refactoring Considerations +- Always return the object being modified +- Don't break the chain (no functions that return NULL) +- Maintain consistent naming (set_*, add_*, etc.) +- Document order dependencies + +### 6. Format String DSL (Domain-Specific Language) + +#### Pattern Description +`f_str()` creates a mini-language for specifying numeric formatting. + +#### Why This Pattern? +- **Declarative**: Users specify what they want, not how to get it +- **Compact**: Single line specifies format and statistics +- **Metadata Capture**: Format string contains information for processing + +#### Implementation in Tplyr + +```r +# Format string captures multiple pieces of information +f_str('xx.x (xx.xx)', mean, sd) + +# Parsed to extract: +# - Format: 'xx.x (xx.xx)' +# - Statistics: mean, sd +# - Integer widths: 2, 2 +# - Decimal precisions: 1, 2 +# - Combination: both in same string +``` + +#### Key Characteristics +- 'x' represents digits +- 'a' represents auto-precision +- 'X' or 'A' triggers parenthesis hugging +- Multiple statistics can be combined +- Row label comes from left side of `=` in `set_format_strings()` + +#### Refactoring Considerations +- Format string parsing is complex - don't break it +- Test all format string features +- Maintain backward compatibility of syntax +- Document any new format string features + +### 7. Strategy Pattern for Denominators + +#### Pattern Description +Different denominator calculation strategies are encapsulated and swappable. + +#### Why This Pattern? +- **Flexibility**: Different tables need different denominators +- **Encapsulation**: Complex logic is isolated +- **Testability**: Each strategy can be tested independently + +#### Implementation in Tplyr + +```r +# Different denominator strategies +# 1. Treatment group total (default) +# 2. Population data total +# 3. Custom grouping via set_denoms_by() +# 4. Filtered denominator via set_denom_where() + +# Strategy selected based on layer configuration +calculate_denominator <- function(layer, data) { + if (has_pop_data(layer)) { + # Use population data strategy + } else if (has_custom_denom(layer)) { + # Use custom grouping strategy + } else { + # Use default strategy + } +} +``` + +#### Key Characteristics +- Multiple denominator calculation methods +- Selection based on layer configuration +- Affects percentage calculations +- Critical for correct results + +#### Refactoring Considerations +- Test all denominator strategies +- Verify percentages are correct +- Don't change default behavior +- Document denominator logic clearly + +### 8. Template Method Pattern for Layer Processing + +#### Pattern Description +Layer processing follows a fixed algorithm with customizable steps. + +#### Why This Pattern? +- **Consistency**: All layers follow same overall process +- **Customization**: Each layer type customizes specific steps +- **Maintainability**: Algorithm is in one place + +#### Implementation in Tplyr + +```r +# Template in build.R +build.tplyr_table <- function(x, metadata=FALSE) { + # 1. Pre-processing (same for all) + treatment_group_build(x) + x <- build_header_n(x) + + # 2. Layer processing (customized per layer type) + map(x$layers, process_summaries) # S3 dispatch + map(x$layers, process_formatting) # S3 dispatch + + # 3. Post-processing (same for all) + output <- bind_layers(...) + + # 4. Optional metadata (same for all) + if (metadata) { + map(x$layers, process_metadata) # S3 dispatch + } +} +``` + +#### Key Characteristics +- Fixed overall algorithm +- Customizable steps via S3 dispatch +- Pre and post-processing are consistent +- Layer-specific logic is isolated + +#### Refactoring Considerations +- Don't change overall algorithm without strong justification +- Maintain S3 dispatch points +- Test pre and post-processing separately +- Verify all layer types work with algorithm + +## Architectural Patterns + +### 1.

Breaking Lazy Evaluation + +**Anti-Pattern**: Processing data in constructors + +```r +# BAD +tplyr_table <- function(target, treat_var) { + # Don't do this! + results <- target %>% + group_by(!!treat_var) %>% + summarize(n = n()) + + env(target = target, results = results) +} +``` + +**Correct Pattern**: Store configuration, process in `build()` + +```r +# GOOD +tplyr_table <- function(target, treat_var) { + env(target = target, treat_var = enquo(treat_var)) +} +``` + +### 2. Tight Coupling Between Layers + +**Anti-Pattern**: Layers directly accessing other layers + +```r +# BAD +process_summaries.count_layer <- function(x) { + # Don't access sibling layers + other_layer <- x$parent$layers[[2]] + other_data <- other_layer$built_table +} +``` + +**Correct Pattern**: Layers are independent, combined in post-processing + +### 3.

Test Construction Separately from Execution + +```r +test_that("table construction works", { + tab <- tplyr_table(iris, Species) + expect_s3_class(tab, "tplyr_table") + expect_true(is.environment(tab)) +}) + +test_that("table execution works", { + tab <- tplyr_table(iris, Species) %>% + add_layer(group_count(Species)) + + result <- build(tab) + expect_s3_class(result, "data.frame") +}) +``` + +### 2. Test Each Layer Type + +```r +test_that("count layer processes correctly", { + # Test count-specific logic +}) + +test_that("desc layer processes correctly", { + # Test desc-specific logic +}) + +test_that("shift layer processes correctly", { + # Test shift-specific logic +}) +``` + +### 3. Test Edge Cases + +```r +test_that("handles empty groups", { + # Test with data that has empty treatment groups +}) + +test_that("handles all NA data", { + # Test with all missing values +}) + +test_that("handles single group", { + # Test with only one treatment group +}) +``` + +## Performance Patterns + +### 1. Avoid Repeated Calculations + +**Pattern**: Calculate once, store in environment + +```r +# Calculate header N once +build_header_n <- function(x) { + header_n <- calculate_header_n(x) + env_bind(x, header_n = header_n) + x +} +``` + +### 2.

Now always binds `summary_stat` even when empty, maintaining compatibility with issue #131 fix. + +2. **Test Updates**: Updated tests to reflect correct behavior for empty data handling: + - `test-process_formatting_count.R`: Updated to expect successful build with empty data + - `test-count_helpers.R`: Updated to expect successful build with empty data + +### Code Changes +- `R/count.R::process_count_n()`: Removed early return, always binds `summary_stat` +- `R/count.R::process_summaries.count_layer()`: Added comment explaining why we don't return early for empty data + +## Performance Benchmarking + +**Status**: ⏸️ Not yet completed + +**Reason**: Waiting for test failures to be resolved before benchmarking performance. + +**Plan**: Once tests pass, will run benchmark comparing refactored count layer functions to baseline. + +## Analysis of Failures + +### Why These Failures Occurred + +The failures are occurring at the boundary between refactored and un-refactored code: + +1. **Nested Counts**: The `process_nested_count_target()` function creates sub-layers and processes them using the refactored `process_summaries.count_layer()`. However, it manipulates `denoms_by` in ways that the refactored code handles differently than the original `evalq()`-based code. + +2. **Risk Difference**: The risk difference processing creates count layers and processes them, but the denominator calculations are being affected by how the refactored code handles `denoms_by`. + +### Common Pattern + +Both failures involve: +- Un-refactored code (still using `evalq()`) that creates and processes layers +- Interaction with refactored count layer processing +- Denominator calculations (`denoms_by`) being handled differently + +### Why This Matters + +The refactored code follows the Extract-Process-Bind pattern, which means: +- Variables are explicitly extracted from environments +- Processing happens in function scope +- Results are explicitly bound back + +The un-refactored code using `evalq()`: +- Executes in the layer environment +- Can directly manipulate environment variables +- Has different scoping behavior + +When these two patterns interact, the denominator calculations can produce different results. + +## Recommendations + +### Option 1: Proceed with Nested Count Refactoring (Recommended) +**Pros**: +- Addresses root cause of failures +- Follows the planned task order (Task 21 is next for nested counts) +- Will likely resolve both nested count and potentially risk difference issues + +**Cons**: +- More work before checkpoint passes +- Risk difference may still need separate attention + +**Action**: Move to Task 21 (Refactor nested count functions) and Task 22 (Refactor risk difference functions) + +### Option 2: Investigate and Fix Denominator Calculation +**Pros**: +- Might be a quick fix if it's a simple issue +- Could unblock checkpoint immediately + +**Cons**: +- May be treating symptoms rather than root cause +- Could introduce workarounds that complicate future refactoring +- Might not be possible without refactoring nested counts + +**Action**: Deep dive into denominator calculation differences between refactored and un-refactored code + +### Option 3: Accept Failures and Document +**Pros**: +- Can proceed with other refactoring tasks +- Failures are isolated to specific features +- Will be addressed in future tasks + +**Cons**: +- Checkpoint not fully complete +- R CMD check won't pass +- May indicate deeper issues + +**Action**: Document failures, mark checkpoint as "partially complete", proceed to next tasks + +## Next Steps + +**Immediate**: +1. Get user input on how to proceed +2. If Option 1: Begin Task 21 (nested count refactoring) +3. If Option 2: Investigate denominator calculation differences +4. If Option 3: Document and proceed to Task 10 (desc layer refactoring) + +**After Resolution**: +1. Run full test suite and verify all tests pass +2. Run R CMD check and verify it passes +3. Benchmark performance of count layer functions +4. Document results and mark checkpoint complete + +## Conclusion + +The refactoring of count layer functions has been largely successful, with 99.6% of tests passing. The remaining failures are at the boundary between refactored and un-refactored code, specifically in nested counts and risk difference calculations. These failures are expected given that the related functions haven't been refactored yet. + +The recommended path forward is to proceed with refactoring the nested count and risk difference functions (Tasks 21-22), which will likely resolve these issues at their root cause. diff --git a/.kiro/specs/tplyr-refactor/tasks.md b/.kiro/specs/tplyr-refactor/tasks.md index 73773842..ce7d1e62 100644 --- a/.kiro/specs/tplyr-refactor/tasks.md +++ b/.kiro/specs/tplyr-refactor/tasks.md @@ -6,14 +6,14 @@ This implementation plan breaks down the refactoring of Tplyr's `evalq()` usage ## Task List -- [-] 1.

Tplyr is a mature, production-ready R package used in regulated pharmaceutical environments. Any changes must preserve backward compatibility and maintain the package's qualification status. + +## Critical Principles + +### 1. Backward Compatibility is Paramount + +**Rule**: Never break existing user code without explicit deprecation cycle + +**Rationale**: Tplyr is used in validated pharmaceutical workflows. Breaking changes require revalidation, which is extremely costly for users. + +**Implementation**: +- All existing functions must continue to work with same inputs/outputs +- If changing behavior, use deprecation warnings for at least one release cycle +- Provide migration path for deprecated features +- Document all changes in NEWS.md + +### 2. Preserve Traceability Features + +**Rule**: Metadata and traceability functionality must be maintained or enhanced, never reduced + +**Rationale**: Traceability from summary to source data is a core value proposition for regulatory compliance. + +**Implementation**: +- All refactoring must preserve `build(metadata=TRUE)` functionality +- Metadata structure can be extended but not reduced +- Test metadata generation for all layer types +- Ensure `get_metadata()` and related functions continue to work + +### 3. Maintain Test Coverage + +**Rule**: Refactored code must maintain or improve test coverage + +**Rationale**: High test coverage is essential for confidence in a package used in regulated environments. + +**Implementation**: +- Run full test suite before and after changes +- Add tests for any new code paths +- Update snapshot tests if output format changes (with justification) +- Maintain UAT test suite + +### 4. Respect the Environment-Based Architecture + +**Rule**: Understand and preserve the environment-based object model + +**Rationale**: The environment-based design enables mutable state, parent-child relationships, and lazy evaluation - all core to Tplyr's design. + +**Implementation**: +- Don't convert environments to lists or other structures without careful consideration +- Preserve parent-child relationships between tables and layers +- Maintain lazy evaluation pattern (construction ≠ execution) +- Understand quosure handling for NSE + +## Command Execution Best Practices + +### 1. Git Command Safety + +**Rule**: Prevent git commands from entering interactive paging mode while preserving important information + +**Rationale**: Git commands that produce large output can trigger interactive pagers (like `less`) which hang the terminal and require manual intervention. However, we must balance this with the need to see all relevant information. + +**When to Limit Output**: +- Exploratory commands (checking history, browsing commits) +- Commands where you only need recent/summary information +- Commands that might produce hundreds of lines + +**When NOT to Limit Output**: +- Viewing specific diffs needed for debugging +- Checking for specific errors or patterns +- When the full output is needed for decision-making +- When output is expected to be small (e.g., `git status`) + +**Implementation**: +```bash +# Exploratory/browsing - LIMIT OUTPUT +git log --all --oneline | head -20 # Recent commits +git log --all --oneline -20 # Using git's built-in limit +git branch -a | head -30 # List branches + +# Specific information needed - USE GREP/FILTER +git log --all --oneline | grep "refactor" # Find specific commits +git diff HEAD~1 | grep -A 5 "function" # Find specific changes + +# Full output needed for analysis - DON'T LIMIT +git status # Usually short +git diff path/to/specific/file.R # Specific file diff +git show commit_hash:path/to/file # Specific file content + +# Test output - SHOW SUMMARY +Rscript -e "devtools::test()" 2>&1 | tail -100 # Show end with summary +Rscript -e "devtools::test()" 2>&1 | grep -E "(FAIL|WARN|PASS|Duration)" # Just stats + +# Test output - SHOW FAILURES +Rscript -e "devtools::test()" 2>&1 | grep -A 20 "FAIL" # Show failure details + +# Use --no-pager for git when piping +git --no-pager log --oneline -20 +git --no-pager diff HEAD~1 | head -100 +``` + +**Best Practice**: Start with limited output for exploration, then run specific commands without limits when you need full details. + +### 2. Test Output Management + +**Rule**: Always limit test output to prevent terminal overflow + +**Implementation**: +- Use `tail -N` to show only the last N lines of test output +- Use `grep` to filter for specific patterns +- Examples: + ```bash + # Show only summary + Rscript -e "devtools::test()" 2>&1 | tail -50 + + # Show only failures + Rscript -e "devtools::test()" 2>&1 | grep -A 10 "FAIL" + ``` + +## Code Quality Standards + +### 1. R Package Best Practices + +**Rule**: Follow standard R package development practices + +**Implementation**: +- Use roxygen2 for documentation +- Follow tidyverse style guide +- Pass `R CMD check` with no errors, warnings, or notes +- Maintain CRAN compliance + +### 2. Documentation Requirements + +**Rule**: All changes must be documented + +**Implementation**: +- Update function documentation for any API changes +- Update relevant vignettes +- Add examples for new features +- Update NEWS.md with user-facing changes + +### 3. Code Organization + +**Rule**: Maintain clear separation of concerns + +**Implementation**: +- Keep related functionality in same file +- Use consistent naming conventions +- Separate user-facing API from internal implementation +- Use `@noRd` for internal functions + +## Testing Requirements + +### 1. Test Before Refactoring + +**Rule**: Establish baseline test results before making changes + +**Implementation**: +```r +# Run full test suite +devtools::test() + +# Run R CMD check +devtools::check() + +# Document baseline results +``` + +### 2. Test During Refactoring + +**Rule**: Run tests frequently during refactoring + +**Implementation**: +- Run relevant tests after each logical change +- Don't accumulate untested changes +- Fix test failures immediately + +### 3. Test After Refactoring + +**Rule**: Comprehensive testing before considering refactoring complete + +**Implementation**: +- Full test suite must pass +- R CMD check must pass +- Manual testing of examples in vignettes +- Performance testing if relevant + +## Refactoring Strategies + +### 1. Incremental Changes + +**Rule**: Make small, testable changes rather than large rewrites + +**Rationale**: Small changes are easier to test, review, and debug. They also reduce risk. + +**Implementation**: +- Refactor one module at a time +- Commit working code frequently +- Each commit should leave code in working state + +### 2. Extract Before Modify + +**Rule**: When refactoring complex functions, extract helper functions first + +**Implementation**: +1. Extract logical chunks into helper functions +2. Test that extraction didn't change behavior +3. Refactor helper functions individually +4. Test again + +### 3. Parallel Implementation + +**Rule**: For major changes, implement new version alongside old + +**Implementation**: +- Create new functions with different names +- Migrate functionality gradually +- Deprecate old functions once new ones are stable +- Remove deprecated functions after deprecation cycle + +## Specific Tplyr Considerations + +### 1. Layer Processing + +**Rule**: Understand the three-phase layer processing model + +**Phases**: +1. `process_summaries()`: Calculate numeric results +2. `process_formatting()`: Apply string formatting and pivot +3. `process_metadata()`: Generate traceability information + +**Implementation**: +- Changes to one phase should not break others +- Test all three phases for each layer type +- Maintain S3 dispatch pattern + +### 2. Format Strings + +**Rule**: Preserve `f_str()` functionality and syntax + +**Rationale**: Format strings are a core DSL that users rely on + +**Implementation**: +- Don't change format string parsing without strong justification +- Maintain support for: x-based width, auto-precision (a), parenthesis hugging (X/A) +- Test all format string features + +### 3. Quosures and NSE + +**Rule**: Maintain tidy evaluation patterns + +**Implementation**: +- Use `enquo()`, `enquos()` for capturing user inputs +- Use `!!` for unquoting +- Use `as_name()` for converting quosures to strings +- Test with both quoted and unquoted inputs + +### 4. Factor Handling + +**Rule**: Preserve factor-based ordering and dummy value generation + +**Implementation**: +- Test with factor and non-factor inputs +- Verify factor levels are respected in output +- Ensure dummy rows are generated for all factor levels + +### 5. Population Data + +**Rule**: Maintain separation between target and population datasets + +**Implementation**: +- Test with and without separate population data +- Verify denominators calculated correctly +- Ensure header N values use population data when specified + +## Performance Considerations + +### 1. Don't Optimize Prematurely + +**Rule**: Maintain correctness over performance unless performance is a documented issue + +**Implementation**: +- Profile before optimizing +- Document performance improvements with benchmarks +- Don't sacrifice readability for minor performance gains + +### 2. Benchmark Major Changes + +**Rule**: If refactoring could affect performance, measure it + +**Implementation**: +```r +# Use microbenchmark or bench +library(bench) +mark( + old_version = old_function(...), + new_version = new_function(...), + iterations = 100 +) +``` + +## Deprecation Process + +### 1. Deprecation Warnings + +**Rule**: Use lifecycle package for deprecation warnings + +**Implementation**: +```r +#' @export +old_function <- function(...) { + lifecycle::deprecate_warn( + when = "1.3.0", + what = "old_function()", + with = "new_function()" + ) + # ... existing implementation +} +``` + +### 2. Deprecation Timeline + +**Rule**: Minimum one release cycle for deprecation + +**Timeline**: +1. Release N: Add deprecation warning, document alternative +2. Release N+1: Mark as deprecated in documentation +3. Release N+2: Consider removal (or keep indefinitely if low cost) + +## Code Review Checklist + +Before considering refactoring complete, verify: + +- [ ] All existing tests pass +- [ ] R CMD check passes with no errors/warnings/notes +- [ ] New tests added for any new code paths +- [ ] Documentation updated (functions, vignettes, NEWS.md) +- [ ] Backward compatibility maintained or deprecation warnings added +- [ ] Metadata generation still works +- [ ] Examples in vignettes still run +- [ ] Performance is acceptable (benchmark if relevant) +- [ ] Code follows tidyverse style guide +- [ ] Commit messages are clear and descriptive + +## Common Pitfalls to Avoid + +### 1. Breaking Quosure Handling + +**Pitfall**: Treating quosures as regular values + +**Solution**: Use `as_name()`, `eval_tidy()`, etc. appropriately + +### 2. Changing Output Structure + +**Pitfall**: Modifying column names or structure of output data frame + +**Solution**: Output structure is part of the API - changes require deprecation + +### 3. Ignoring Edge Cases + +**Pitfall**: Testing only happy path + +**Solution**: Test with empty data, single group, all NA, etc. + +### 4. Forgetting About Sublayers + +**Pitfall**: Testing only top-level layers + +**Solution**: Test nested count layers and other sublayer scenarios + +### 5. Breaking S3 Dispatch + +**Pitfall**: Changing method signatures without updating all implementations + +**Solution**: Verify all S3 methods for a generic have consistent signatures + +## When to Seek Help + +Consult with Tplyr maintainers or experienced R developers when: + +- Considering changes to core architecture (environment model, S3 dispatch) +- Unsure about backward compatibility implications +- Encountering complex quosure/NSE issues +- Planning to change output structure +- Considering performance optimizations that affect readability +- Dealing with CRAN submission issues + +## Resources + +### Internal Documentation +- Codebase mapping: `.kiro/specs/tplyr-refactor/codebase-mapping.md` +- Functional requirements: `.kiro/specs/tplyr-refactor/functional-requirements.md` + +### External Resources +- [Advanced R - Environments](https://adv-r.hadley.nz/environments.html) +- [Advanced R - Metaprogramming](https://adv-r.hadley.nz/metaprogramming.html) +- [R Packages Book](https://r-pkgs.org/) +- [Tidyverse Style Guide](https://style.tidyverse.org/) +- [Tplyr Vignettes](vignettes/) + +## Conclusion + +Refactoring Tplyr requires careful attention to backward compatibility, testing, and documentation. The package's use in regulated environments means that reliability and traceability are more important than code elegance.

However, it manipulates `denoms_by` in ways that the refactored code handles differently than the original `evalq()`-based code. - -2. **Risk Difference**: The risk difference processing creates count layers and processes them, but the denominator calculations are being affected by how the refactored code handles `denoms_by`. - -### Common Pattern - -Both failures involve: -- Un-refactored code (still using `evalq()`) that creates and processes layers -- Interaction with refactored count layer processing -- Denominator calculations (`denoms_by`) being handled differently - -### Why This Matters - -The refactored code follows the Extract-Process-Bind pattern, which means: -- Variables are explicitly extracted from environments -- Processing happens in function scope -- Results are explicitly bound back - -The un-refactored code using `evalq()`: -- Executes in the layer environment -- Can directly manipulate environment variables -- Has different scoping behavior - -When these two patterns interact, the denominator calculations can produce different results. - -## Recommendations - -### Option 1: Proceed with Nested Count Refactoring (Recommended) -**Pros**: -- Addresses root cause of failures -- Follows the planned task order (Task 21 is next for nested counts) -- Will likely resolve both nested count and potentially risk difference issues - -**Cons**: -- More work before checkpoint passes -- Risk difference may still need separate attention - -**Action**: Move to Task 21 (Refactor nested count functions) and Task 22 (Refactor risk difference functions) - -### Option 2: Investigate and Fix Denominator Calculation -**Pros**: -- Might be a quick fix if it's a simple issue -- Could unblock checkpoint immediately - -**Cons**: -- May be treating symptoms rather than root cause -- Could introduce workarounds that complicate future refactoring -- Might not be possible without refactoring nested counts - -**Action**: Deep dive into denominator calculation differences between refactored and un-refactored code - -### Option 3: Accept Failures and Document -**Pros**: -- Can proceed with other refactoring tasks -- Failures are isolated to specific features -- Will be addressed in future tasks - -**Cons**: -- Checkpoint not fully complete -- R CMD check won't pass -- May indicate deeper issues - -**Action**: Document failures, mark checkpoint as "partially complete", proceed to next tasks - -## Next Steps - -**Immediate**: -1. Get user input on how to proceed -2. If Option 1: Begin Task 21 (nested count refactoring) -3. If Option 2: Investigate denominator calculation differences -4. If Option 3: Document and proceed to Task 10 (desc layer refactoring) - -**After Resolution**: -1. Run full test suite and verify all tests pass -2. Run R CMD check and verify it passes -3. Benchmark performance of count layer functions -4. Document results and mark checkpoint complete - -## Conclusion - -The refactoring of count layer functions has been largely successful, with 99.6% of tests passing. The remaining failures are at the boundary between refactored and un-refactored code, specifically in nested counts and risk difference calculations. These failures are expected given that the related functions haven't been refactored yet. - -The recommended path forward is to proceed with refactoring the nested count and risk difference functions (Tasks 21-22), which will likely resolve these issues at their root cause. diff --git a/.kiro/specs/tplyr-refactor/code-quality-review.md b/.kiro/specs/tplyr-refactor/code-quality-review.md new file mode 100644 index 00000000..41472c93 --- /dev/null +++ b/.kiro/specs/tplyr-refactor/code-quality-review.md @@ -0,0 +1,316 @@ +# Code Quality Review - Task 26 + +## Date: December 7, 2025 + +## Overview + +This document summarizes the code quality review conducted for the Tplyr refactoring project.

Unclear Data Flow + +It was difficult to determine what a function read from and wrote to the environment: + +```r +# What does this function modify? +process_summaries.count_layer <- function(x, ...) { + evalq({ + # 200 lines of code... + # What gets modified? Hard to tell! + }, envir=x) +} +``` + +### 3. Testing Challenges + +Testing required full table/layer setup, making unit tests cumbersome: + +```r +# Hard to test specific logic +test_that("treatment_group_build works", { + # Need full table setup + table <- tplyr_table(data, treat) %>% + add_layer(...) %>% + # ... more setup + + treatment_group_build(table) + # Can only test end result, not intermediate steps +}) +``` + +### 4. Debugging Difficulty + +When errors occurred inside `evalq()`, stack traces were confusing and variables were hard to inspect. + +## The Pattern in Detail + +### Extract Phase + +The extract phase explicitly retrieves all needed values from the environment: + +```r +# EXTRACT: Get what we need from environment +target <- table$target +treat_var <- table$treat_var +pop_data <- table$pop_data +pop_treat_var <- table$pop_treat_var +table_where <- table$table_where +pop_where <- table$pop_where +treat_grps <- table$treat_grps +cols <- table$cols +``` + +**Key Points:** +- Use `$` accessor for direct environment access +- Use `env_get()` for inherited values: `env_get(x, "built_target", inherit = TRUE)` +- Use `env_get()` with defaults: `env_get(x, "include_total_row", default = FALSE)` +- Extract ALL needed values at the start +- Group related extractions together + +### Process Phase + +The process phase performs all calculations in the function's own environment: + +```r +# PROCESS: Work in function environment (no side effects) +built_target <- clean_attr(target) + +if (!is.factor(target[[as_name(treat_var)]])) { + built_target <- built_target %>% + mutate(!!treat_var := factor(!!treat_var)) +} + +# Local variables stay local +fct_levels <- unique(c( + levels(built_pop_data[[as_name(pop_treat_var)]]), + levels(built_target[[as_name(treat_var)]]), + names(treat_grps) +)) + +# More processing... +``` + +**Key Points:** +- All variables are local to the function +- No side effects on table/layer environment +- Temporary variables don't need cleanup +- Easy to debug with standard R tools +- Can use standard control flow + +### Bind Phase + +The bind phase explicitly writes results back to the environment: + +```r +# BIND: Explicitly write results back +table$built_target <- built_target +table$built_pop_data <- built_pop_data + +invisible(table) +``` + +**Key Points:** +- Only write what needs to persist +- Use `$` accessor for direct binding +- Use `env_bind()` for multiple bindings: `env_bind(x, var1 = val1, var2 = val2)` +- Return invisibly to maintain method chaining +- Document what gets bound in function documentation + +## Implementation Examples + +### Example 1: Simple Environment Modifier + +```r +#' Build header N values +#' +#' This function follows the Extract-Process-Bind pattern: +#' 1.
