Thanks James! There are something that I am not sure yet and please take a 
look at below.

I get access to R of unix version (on a Sunny computer) from my desk top 
(running Windows XP) through SSH secure shell.

readline is available on our server side. Do I need to ask a system 
administer to re-compile R with adding readline?

I added Xemacs to my account on the server and was able to initiate the 
Xemacs:*scratch* window. But I do not know how to run R from within Xemacs. 
I can type commands and initiate xterm window. It gave me an error message, 
however, when I tried to run R on the Xemacs Shell command: "fatal error: 
you must specify '--save', '--no-save' or '--vanilla'".

On my desktop computer I did not find any file called init.el to which I 
can add your script. Is this an alternative to the two ways described 
above?

I greatly appreciate your help!
