I realize that it is now legal in R to use underscores, since they no longer
represent the same thing as "->". But I don't consider "legal" the same as
"encouraged", do you?
Probably the context most important is if you need to be able to share code
with S-Plus. I work exclusively in R, but have academic colleagues who use
S-Plus. As far as I know, S-Plus still restricts the use of "_", and for me,
that possibility is enough to justify suggesting that people not use "_". I
personally find that syntax hard to read, as well.
I don't consider it all that important an issue, especially as I know that
many people disagree with me, and never use S-Plus, and don't care about
appearance as long as it works. I would never have brought it up as an issue
on its own, but did feel inclined to tack it on as a postscript to a
question I did answer appropriately.
I shan't mention it again!
