[ESS] Read R manuals inside emacs

[Naresh Gurbuxani]

On my Mac installation of R, below documents are included in RHOME/doc/manual:
R-intro.html
R-data.html
[others]

Is it possible to read them from inside emacs (for example in info)? 

One of the files (RHOME/share/man/man1/R.1) says, to access R manuals, type
info -f R-intro

Where should this command be typed?

Finally, is this the right mailing group for this question?

Thanks,
Naresh
