If I recall correctly, it's because of the way the ess-history-file variable is
set in the ESS code. The following works for me:
(defun ei-no-rhistory ()
(setq ess-history-file "/dev/null"))
(add-hook 'inferior-ess-mode-hook 'ei-no-rhistory)
where "ei" in the function name is just my initials. See if that works for you.
You can change /dev/null to whatever you want. There may be a cleaner solution,
but I was just happy not to find .Rhistory files all over the place, which
bother me greatly for some unknown reason :).
