file=R/check_group_variation.R,line=307,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=307,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=292,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.

file=R/check_group_variation.R,line=150,col=3,[object_overwrite_linter] 'by' is an exported object from package 'base'. Avoid re-using such symbols.

file=R/check_factorstructure.R,line=230,col=3,[return_linter] Use implicit return behavior; explicit return() is not needed.

file=R/check_collinearity.R,line=595,col=3,[object_overwrite_linter] 'R' is an exported object from package 'tools'. Avoid re-using such symbols.

file=R/check_collinearity.R,line=552,col=7,[outer_negation_linter] !all(x) is better than any(!x). The former applies negation only once after aggregation instead of many times for each element of x.

file=R/check_collinearity.R,line=540,col=13,[paste_linter] Use paste(), not paste0(), to collapse a character vector when sep= is not used.
