I agree with Peter here. But it did make me pause the first time I read it on the help page years ago and furthermore, I think this is at least the second time where this particular formulation has been questioned on R-devel. I am not an index of R help pages, but I cannot recall seeing the 'L' as shorthand for logical. I suggest changing the formulation since it seems that several people have been confused, for example by writing out 'logical' instead of 'L'.
