This linter checks for 1:length(...), 1:nrow(...), 1:ncol(...),
1:NROW(...) and 1:NCOL(...) expressions in base-R, or their usage in
conjunction with seq() (e.g., seq(length(...)), seq(nrow(...)), etc.).
Details
Additionally, it checks for 1:n() (from dplyr) and 1:.N (from data.table).
These often cause bugs when the right-hand side is zero.
It is safer to use base::seq_len() or base::seq_along() instead.
