metacoder 0.3.7

  • Maintenance release to fix CRAN check issues.

metacoder 0.3.6

  • When an ordered factor is supplied to the groups argument of compare_groups, the order of levels is used to arrange the results. This can be used to change the order of groups when the output is used with heat_tree_matrix (issue #323).
  • Added calc_diff_abund_deseq2 function to use DESeq2 to produce output like compare_group useful for heat_tree_matrix
  • Fixed error with primersearch and primersearch_raw when there is a single match to a single query (issue #326)
  • Fixed Error in grid.Call.graphics(C_setviewport, vp, TRUE) : non-finite location and/or size for viewport when using heat_tree_matrix with only a single comparison. Now a single differential heat tree is made instead of a matrix #328).
  • Replace use of depreciated n_extra in print.

metacoder 0.3.5

  • Replaced depreciated as.tbl function from dplyr'
  • Added node_legend_title and edge_legend_title options to heat_tree to specify the title for each legend.
  • Added options to heat_tree to set the number of significant figures used for the numbers in the legend.
  • Reintegrated the functionality of the taxa package in order to prepare for releasing a rewritten version of taxa.
  • Reduced the number of dependencies and made some optional.

metacoder 0.3.4

  • Added parsing of taxon ranks to the UNITE parser
  • Various minor bug fixes

metacoder 0.3.3

  • Fixed a bug in calc_n_samples and calc_prop_samples that caused an error when group names had spaces in them.
  • calc_prop_samples default output column name changed from "n_samples" to "prop_samples".

metacoder 0.3.2

  • calculation functions that use the groups option now warn if groups is used without cols.
  • Fixed a bug in some calculation functions that would name columns incorrectly in some data sets when the groups option was used. (issue #233).

metacoder 0.3.1

Bug fixes

  • calc_taxon_abund no longer errors when a taxon has no observations associated with it.
  • New heat_tree_matrix options to change size and color of row and column labels.
  • Fixed a bug causing the size legend not to be shown (issue #249.
  • Now when a node_color_interval is set but a edge_color_interval is not and edge_color is not used, the edge_color_interval is the same as the node_color_interval.

New features

  • Added parser for dada2 results called parse_dada2 and writers to convert back called make_dada2_asv_table and make_dada2_tax_table.

Changes

  • Started using the viridis colors for heat_tree by default (issue #133.

metacoder 0.3.0

Bug fixes

  • Fixed bug in calc_n_samples where the message reported the number of taxa instead of the number of rows in the table.
  • Fixed bug in heat_tree_matrix that happened when factors were used for treatments (issue #240.
  • zero_low_counts now ignores NAs instead of odd error.
  • compare_groups now ignores NAs instaed of returning NaN

Improvements

  • Added more_than option to calc_n_samples so that users can set the minimum threshold for whether a sample is counted or not instead of it always 1.
  • Added calc_prop_samples function for calculating the proportion of samples with a value greater than 0 (issues #233.
  • primersearch is faster and takes less memory by using ape::DNAbin objects internally.
  • Made calc_taxon_abund about 5x faster.

New features

  • taxmap objects can be converted to phyloseq objects using as_phyloseq.
  • Added parser for uBiome data.

Changes

  • primersearch now takes and returns a taxmap object with results added as tables. primersearch_raw is a new function that behaves like the old primersearch did, returning a table.
  • The dataset option of many functions has been renamed to data to match the option name in the taxa package.
  • Numerous spelling fixes.

metacoder 0.2.1

Bug fixes

  • Fixes numerous bugs in heat_tree_matrix that happen when the input data is not exactly like that produced by compare_groups (issues #195, #196, #197).
  • Fixed how output_file was used with heat_tree_matrix. Now whole plot is saved instead of last subplot. (issue #203)
  • Fixed "unused argument" bug in parse_mothur_tax_summary when reading from a file path (issue #211).
  • Fixed bug when in zero_low_counts when using use_total = TRUE (issue #227).
  • Numerous other small fixes.
  • Fixed parse_phyloseq error when arbitrary rank names were used.

Improvements

  • Node and edge legends can now be excluded individually (Thanks @grabear!) (issue #202).
  • The output of heat_tree_matrix always has a 1:1 aspect ratio. (issue #205)
  • Numerous calculation functions added, with more consistent behavior.

metacoder 0.2.0

Bug fixes

  • Fixed bug in subtaxa that caused an error when all of subset is FALSE. (issue #143)
  • Fixed bug in filter_taxa that caused an error when all taxa are filtered out. (issue #144)

Breaking changes

  • All taxmap-related manipulation functions have been moved to the taxa package.
  • heat_tree now uses the taxmap class defined in the taxa package.
  • Numerous changes (i.e. upgrades) to primersearch

Improvements

  • Upgraded primersearch output to be cleaner and have info like the amplicon sequence and primer binding sites.
  • Added functions to identift and remove taxa with ambiguous names like "unknown"
  • code from ggrepel package now used to avoid overlapping labels. Thanks Kamil Slowikowski!
  • New function heat_tree_matrix to make plotting a pairwise matrix of heat trees for comparing treatments.
  • New parser named parse_mothur_tax_summary for mothur *.tax.summary file made by classify.seqs.
  • New parser named parse_mothur_taxonomy for mothur *.taxonomy file made by classify.seqs.

metacoder 0.1.3

Improvements

  • Provided helpful error message when the evaluation nested too deeply: infinite recursion / options(expressions=)? occurs due to too many labels being printed.
  • heat_tree: improved how the predicted bondries of text is calcuated, so text with any rotation, justification, or newlines influences margins correctly (i.e. does not get cut off).
  • heat_tree: Can now save multiple file outputs in different formats at once

Minor changes

  • heat_tree now gives a warning if infinite values are given to it
  • extract_taxonomy: There is now a warning message if class regex does not match (issue #123)
  • heat_tree: Increased lengend text size and reduced number of labels

Breaking changes

  • The heat_tree option margin_size funcion now takes four values instead of 2.

Bug fixes

  • Fixed bugs caused by dplyr version update
  • Fixed bug in heat_tree that made values not in the input taxmap object not associate with the right taxa. See this post.
  • extract_taxonomy: Fixed an error that occured when not all inputs could be classified and sequences were supplied
  • Fixed bug in primersearch that cased the wrong primer sequence to be returned when primers match in the reverse direction
  • Fixed a bug in parse_mothur_summary where "unclassified" had got changed to "untaxmap" during a search and replace
