This is a bit of a long tale, involving R, Emacs, Screen and ssh.
I connect to our linux server for running R from my linux machine.
On our server, I use GNU Screen to keep persistent sessions.
Recently, I logged into the server using
ssh user at server
but forgot to include the -X switch to forward X.
I started a screen session,
in that, I opened Emacs, and started an instance of R within ESS.
After loading my data sets, I logged out.
The next day, I logged in using
ssh -X user at server
checked my DISPLAY variable (localhost:10.0),
reconnected my screen session using
and set the DISPLAY variable - so, within screen, I can now open kcalc
Switching to the emacs window, in R, when I run
however, I then execute
to update R
then the command
opens a plot window....
However, dev.new() only opens a pdf device...
How can I tell R that there is now a valid X11 device and it should use it?
