Prof. Hastie,
Presumably somewhere in your~/.emacs file you may have a reference to:
(setq inferior-ess-r-help-command ...)
Either add the following or replace the above if present, with:
(setq inferior-ess-r-help-command "help(\"%s\", help_type=\"html\")\n")
Note that the above requires ESS 5.5 or greater.
If you are interested Vincent Goulet has a binary DMG for Emacs 23 and ESS 5.8
here:
http://vgoulet.act.ulaval.ca/en/ressources/emacs/mac
which might save you some time if you wish to update Emacs. I don't use it as I
build Emacs 23 from CVS, but a quick look suggests that he might not yet have
added the above help fix for R 2.11.0.
HTH,
Marc Schwartz
