I often run long R scripts when I start my R environment. I would like to be able to load / run the R script in Emacs / ESS and continue other work in another buffer.
When I press C-g or C-c C-c the process is interrupted, and I must restart the script.
What is the best way to background the R process in ESS / Emacs?
EDIT: Thank you for your answers and comments, but none of them address the fact that Emacs freezes when you load / run a large script and you can't change buffer.
I suppose my question is a little more general - can Emacs background a process to let you keep working?
