Hello there,

after I sent the last message I killed Emacs and restarted it with the "-q"
option (no .emacs file); then I manually loaded ess-site and then started
R.  Now if I do C-c C-v to get help on a function I do get the help in an
Emacs buffer.  I think this is sufficient to conclude that the problem lies
in my initialization file.  Over the years I collected a lot of stuff in
there, I probably won't be easy to find the culpright, but that is my

Thanks to Stephen and Martin for their help, and also to all contributors
for such a good package,
