What OS are you using? It's certainly possible to do what you ask.
However, I like using up and down to move the cursor in the buffer,
and the default settings on my system (Debian GNU/Linux) have
Control-up and Control-down bound to the history commands. That's much
better than esc-p and esc-n for me. Also, on PC keyboards, alt and esc
do the same thing, except that you have to hold down the alt key. So
alt-p and alt-n should also work for you.
If you remain unconvinced, I think this will work for you:
(defun my-ess-mode-hook ()
(local-set-key [up] 'comint-previous-input)
(local-set-key [down] 'comint-previous-input))
(add-hook 'ess-mode-hook 'my-ess-mode-hook)
