You are hooking into R mode, so you need to open an .R file for this to
work.  If you just open dired or any other file it will not work.

This is a better way that should work from any tramp file:

(defun R+ ()
  (let ((inferior-R-program-name)
        (if (and buffer-file-name
                 (file-remote-p buffer-file-name))

M-x R+ will do the right thing.

BTW, I think it would make sense to add inferior-R-remote-program-name
to ESS and to perform the above automatically?
