Hi, Patrick.  You may have already mentioned this, but I wonder what versions of Emacs and ESS you're using.  I'm running Emacs 23.2-19 on a Fedora 15 (linux) system and ESS 5.11.  My system does have ess-eldoc:

    $ locate ess-eldoc
    /usr/share/emacs/site-lisp/ess/ess-eldoc.elc


Can you check to see if you have a similar file on your system?


I have the following in my .emacs file:

    (require 'ess-eldoc)

with NO prior path information specified in the file, and I do get a pop-up list of function arguments when I start to type a function, as:

    x <- rnorm(

In my case this works in the source-code buffer (foo.R) but NOT in the R buffer itself (*R*).
