Configure XEmacs+ESS 5.2.3 under linux FC1

[Xiyan Lon]

Dear u"ESS"er,

I want to know how to install and configure
XEmacs+ESS(5.2.3) on linux (FC1).
I usually use R under XEmacs+ESS on windows 2000
(explained John Fox:
http://socserv.mcmaster.ca/jfox/Books/Companion/ESS/index.html)
I know XEmacs include a package ess (I think old
version) and I can do 

$ xemacs -f R

but I did not see R.
I know Paul Johnson have a rpm ess-emacs
(http://lark.cc.ku.edu/~pauljohn/software/favoriteEmacsFiles/ess-emacs-5.2.2-1fc2.src.rpm)
I rebuild it for fc1 and have installed this rpm and
run very nice in my emacs. Because I did not use emacs
(I want only use XEmacs), how could I configure my
init.el.

Thank for your help.
Best regrads,
Xiyanlon
