title: How can I background the R process in ESS / Emacs?
body: <p>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. </p>
  
  <p>When I press C-g or C-c C-c the process is interrupted, and I must restart the script.</p>
  
  <p>What is the best way to background the R process in ESS / Emacs?</p>
  
  <p>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.</p>
  
  <p>I suppose my question is a little more general - can Emacs background a process to let you keep working?</p>
