[R] Removing trailing spaces

[Patrick Connolly]

Some years ago when I used S-PLUS, I seem to remember, there was a
discussion about a simple method of removing trailing spaces from
vector elements.  I'd be fairly sure the same would work in R, but I
can't find any mention of anything like it in the R archives or with
help.search().

There are ways I could do it with substring(), but I seem to remember
there was something more elegant.  I can find the strip function in
the clim.pact package, but that trims everything after the first space
which is not useful in this case.

Someone please refresh my memory.

TIA
