I don't remember the source as I was reading widely all over the place trying to get up to speed with R in a hurry (having found this group was one of the best sources).

What I read doesn't seem to be incorrect however (it may even have been an archived message here), the *language* itself does not seem to support block *comments*. Using conditional constructs, or an IDE/editor to achieve similar results is a work around - but not the same. I don't mean to nitpick, but as a computer scientist I see this as different :-)

I'll have to look at ESS though.

Thanks,
Esmail

ps: Ah, I seem Meta-; works as a toggle in emacs/ESS .. thanks for encouraging

     me to look at that some more.
