[R] Merge?

[R. Herold]

I see that feature freeze for a better than ever R has been announced. May I
ask if there will be or could be "merge" function for data frames? I believe
it would be very nice if this were "centrally" implemented (with regard to
my humble steps to writing such a function and the related error and other
precautions). I know from VR2R.pdf (courtesy Profs. Venables and Ripley)
that the "Functions crosstabs [...], by and merge [...] do not exist in R.",
but perhaps someone can suggest such a merge function, just as a "by"
function was suggested by Peter Dalgaard on 31. January?

Thank You, Ralf Herold
