[R] ESS with Xemacs? [vs. Emacs, slightly off topic]

[Agustin Lobo]

Happy 2002 to everyone.

I'm following Greg's directions (with some pain, as I'm not
an experienced (x)emacs user) and I find that I cannot use 
fix() in the R session. 
Before trying (x)emacs I normally had
a "raw" R sesion in an xterm and an editor in another window.
When I was done writing the function I run fix() and copied and pasted
the function to the editor session that had been opened by fix().
 
I understand that, using (x)emacs I can save the function to a
text file and source() it in R, but this seems like an odd
procedure considering that both R and the function are in 
windows of the same (x)emacs environment. Is there any simpler
way of passing the edited function to R?

By the way, is there an R-oriented guide or tutorial
to (x)emacs?

Thanks
