As an alternative to the workaround Lionel provided, I added the
following to my .emacs. It stops the problem, and you can get eldoc
information about function arguments if you request it.

;; Show eldoc information only if requested

(setq eldoc-idle-delay 0)

(defun eldoc-message-now ()
  (interactive))

(defun eldoc--message-command-p (command)
  (eq command 'eldoc-message-now))

(add-hook 'ess-mode-hook
  '(lambda() (local-set-key (kbd "C-c e") 'eldoc-message-now)))

(eldoc-add-command 'eldoc-message-now)
