In ESS/Emacs, how can I get the R process buffer to scroll to the bottom after a C-c C-j or C-c C-r

In ESS when I am evaluating chunks of code in a .R file using C-c C-j or C-c C-r (to send the line or region to a running R process), how can I get the R buffer to scroll down automatically, such that after evaluating a region the cursor is at the bottom, at the prompt?

Thanks.

Solution

  • Probably a bunch of ways to do it. In my .emacs.d I have

      (setq comint-prompt-read-only t)
  (setq comint-scroll-to-bottom-on-input t)
  (setq comint-scroll-to-bottom-on-output t)
  (setq comint-move-point-for-output t)
