Relevant features of new R versions

[Bisaloo]

This is a bookmark issue to keep in mind the features we could leverage from the newer R versions in cases we accept to bump the minimum required R version in the future:

• R 3.6.0

  • delayed S3 registration: opens up the possibility of a as.cimg method for rimg objects even though imager is in Suggests
  • use hcl.colors(n, palette = "cividis") instead of viridisLite::cividis(n) (removes the viridisLite dependency): see PR #184

• R 4.0.0

  • don't import plot/plot.default (it's in base and not in graphics anymore)
  • use the palette.colors() function to specify colourblind friendly colour palettes: see PR #184
  • use list2DF() instead of do.call(cbind, ...)

• R 4.1.0

  • Use native pipe |> in examples etc. I like pipes (TW).
  • apply(x, MARGIN, FUN, simplify = FALSE) instead of lapply(seq_len(nrow/ncol(x)), FUN)

• R 4.4.0

  • val <- val %||% default, particularly useful to set defaults to arguments, as in https://github.com/rmaia/pavo/blob/a3e3986083756bfe5c0e07dbe3591e53e29cfba8/R/segplot.R#L48-L62

Dependency upgrades blocked by minimum R version

• R 4.0.0

  • rgl 0.103.5 (see #210)

Just a reminder that bumping the minimum R version should also be the opportunity to remove code added to ensure compatibility with older version (e.g., stringAsFactors(), getRversion() branches, etc.)
