[R] Does anyone else think this might be worth a warning?!?

Hi,
I was *very* surprised by this little trick for new players: mean() only
considers its first argument!
> mean(1,1,2)
[1] 1
> mean(2,1,1)
[1] 2
I found this very different behaviour to max():
> max(1,1,2)
[1] 2
> max(2,1,1)
[1] 2
Perhaps this is the wrong list to ask, but does anyone else think this a
little on the interesting side? Is it not possible to detect a first
argument of length one in the presence of other un-named arguments and
at least produce a warning?
Cheers,
Matthew
