Hi all, I figured out how to get this to work. Not saying this is the best way to do it, but it is working for me. The only problem is that the graphics are very slow (several seconds to draw hist(rnorm(50))!)
First, I changed both /etc/ssh_config and /etc/ssh_configd to allow X11 forwarding (i.e., emacs into those files, find the ForwardAgent and ForwardX11 lines, and change these from "no" to "yes"). Then I used the -X option when ssh'ing into the remote machine: ssh -X myn...@remotecomp. Then I started R remotely. Within the remote R session, I changed the default graphics device from 'quartz' to 'x11': options(device='x11') That's it. It is working, but as I said, is surprisingly slow. Not sure why that is. Does anyone have more experience with graphics remotely? Are they typically slow, or is it my connection, or perhaps a setting?
