[R] emacs + R?

[Giorgio Corani]

Dear All,


As far I as I have understood reading both your past posting and the
documentation, in order to have the  command-line completion facility, I
have to run R within emacs.

However, as I try to start R within emacs as recommended:
C-u M-x R
emacs answers [no match]

the same if I provide the whole path to  the executable:
C-u M-x /usr/bin/R    [no match]

sorry for such beginner question.

regards
