The R buffer in Emacs Speaks Statistics seems to slow down significantly which the line count gets high. Is there a way of limiting the size of the buffer?
Modified this, https://stackoverflow.com/a/11255400/1007926, but was unable to fix the problem.
(add-hook 'ess-tracebug-mode-hook 'ess-tracebug)
(setq comint-buffer-maximum-size 2000)
Is ess-tracebug the correct name of the R buffer? This message appears when the buffer is created:
ess-tracebug mode enabled
This is a partial solution:
C-c C-o (comint-kill-output)
Deletes everything from the last command to the current prompt.
