Pre-release activities - Potential removal of dependencies

[averissimo]

Part of #624 related to vignettes. Please make a PR to pre-release@main

Consider:

• Removal of {magrittr} by importing pipe operator from {dplyr} ✔️ done
• Other packages that can be easily removed ✔️ removed tidyselect as its functions are reexported from dplyr
• Move any of the packages from Depends -> Imports
  • {ggmosaic} ❌ impossible (see below)
  • {ggplot2} ❌ impossible (see below)
  • {shinyTree} ✔️ done
  • {teal.transform} ❌ valid: teal.transform functions should be available to tmg users
  • {teal} ❌ valid: teal dependency is standard in all module packages
  • {shiny} ❌ valid: like teal, module packages use shiny extensively

ggmosaic must stay in Depends as per this note in teal.modules.general.R:

# nolint start
# Note ggmosaic (version <= 0.3.3) needs to be in DEPENDS as the following does not work if it is imported
# df <- data.frame(x = c("A", "B", "C", "A"), y = c("Z", "Z", "W", "W"))
# ggplot(df) + ggmosaic::geom_mosaic(aes(x = ggmosaic::product(x), fill = y))
# nolint end

I experimented with moving it to Imports and it seems to be valid.

ggplot2 will remain in Depends as well as long as ggmosaic has to. It makes no sense to me to have a basic funcitonality in Imports and an enhancement in Depends.

I would actually consider adding @import stats as there are numerous uses of multiple functions. Not necessarily, though, prefixes do add clarity.

The same goes for teal.widgets.

nestcolor is used in most (if not all) examples but nowhere else. I believe it should be upgraded from Suggests to Imports because we don't want those examples to be made conditional.
Alternatively, we can use require(nestcolors) rather than library(nestcolors) in examples.

Thoughts?

[chlebowa]

teal.data should be upgraded from Suggests to Imports as datanames and join_keys is used in many modules, aside from examples.

done

Can you please check if this solves #625. If yes - please close

[chlebowa]

Yes, I got no notes on my last pass.
