[ESS] graphics window for TRAMP sessions

[Fernando Mayer]

I do this normally with TRAMP, however, you need to enable X11 forwarding
both on the client and the server side.

On the client side: edit (or create) ~/.ssh/config to include the following
line

ForwardX11 yes

On the server side: you will need to edit /etc/ssh/sshd_config to
include/enable the following line

X11Forwarding yes

In a normal TRAMP session I'm able to display R graphics on my local
machine.

HTH,
