[ESS] Use of up arrow and down arrow keys

[John Maindonald]

[I forgot to say that I am using ess-5.2.8]

I've just now moved to using Aquaemacs (Mac OS X), from

http://aquamacs.org/

I've had code in my .emacs file that binds the up arrow key
to <ESC>P, etc.  This does not work with Aquaemacs; I get
the message:
   "Symbol's value as variable is void: xemacs-flag"
Is there some way to make the up and down arrow (cursor)
keys work, with my setup?
