From BiocCheck :
- NOTE: Consider shorter lines; 501 lines (14%) are > 80 characters long.
Most of these lines are roxygen comments.
formatR package says :
Also note that single lines of long comments will be wrapped into shorter ones automatically when wrap = TRUE, but roxygen comments will not be wrapped (i.e., comments that begin with #').
Don't tell me I have to do this one line per line. Please.
