Can you clarify a bit about what you mean when you say "emacs can't
find R" -- how does this happen? When does this happen.

Are yo saying that starting R doesn't work from within emacs, eg: `M-x
R` doesn't work for you?

>From what you are saying, it sounds like a PATH problem ... are you
using a "normal" os-x install of R? If you open a terminal and type
`which R` is it in /usr/bin?

Now from inside emacs, is that location that R is in (here /usr/bin)
found in the PATH that emacs sees? If you do:

M-: (getenv "PATH")

Do you use the appropriate directory where R is in listed in the PATH
that emacs just returned in your minibuffer?
