file=R/check_group_variation.R,line=328,col=27,[paste_linter] Use paste(), not paste0(), to collapse a character vector when sep= is not used.

file=R/check_group_variation.R,line=328,col=27,[paste_linter] toString(.) is more expressive than paste(., collapse = ", "). Note also glue::glue_collapse() and and::and() for constructing human-readable / translation-friendly lists

file=R/check_group_variation.R,line=313,col=14,[scalar_in_linter] Use comparison operators (e.g. ==, !=, etc.) to match length-1 scalars instead of %in%. Note that if x can be NA, x == 'arg' is NA whereas x %in% 'arg' is FALSE, so consider extra protection for the missing case in your code.
