Require usage of anyDuplicated() > 0 over any(duplicated(.))
Source:R/any_duplicated_linter.R
any_duplicated_linter.RdanyDuplicated() exists as a replacement for any(duplicated(.)) which is
more efficient for simple objects, and in the worst case is the same
efficiency. Therefore it should be used in all situations instead of the
latter.
Details
Also match usage like length(unique(x$col)) == nrow(x), which can
be replaced by anyDuplicated(x$col) == 0L.
