Salut Vincent,

I had a closer look at the issue with these instructions. Indeed, 'M-x 
Rd-mode RET' works if I install ESS from the source. However, this 
fails with pristine Aquamacs Emacs saying [No match], although this is 
said to come with ESS. The difference may be indeed that essddr.elc is 
not included in Aquamacs. Better keep now that configuration that has

(load "~/Library/ess-5.3.4/lisp/ess-site")

in ~/.emacs file (which also seems to work: I didn't come to think that 
Mac would have a more exotic location).

This is for Rnw files: I've never had trouble with them. However, I now 
have also these lines in my  ~/.emacs:

(add-hook 'Rd-mode-hook
                (lambda ()
                 (abbrev-mode 1)
                 (font-lock-mode 1)))
(add-to-list 'auto-mode-alist '("\\.Rd\\'" . Rd-mode))
(add-to-list 'auto-mode-alist '("\\.rd\\'" . Rd-mode))

and now Rd-mode starts automatically.

Thanks for the help.

Best wishes, Jari Oksanen
