is it possible to display plots in an emacs buffer?

[david.whiting at ncl.ac.uk]

Perpetuating my own sub-thread...

Adding (delete-other-windows) to the function gives the plot the whole
frame, which looks better.  To remove the plot and get back to the the R
prompt just press 'q'.

(defun R-plot-w3m ()
  (interactive)
  (setq ess-command (comint-get-old-input-default))
  (ess-execute "png('/tmp/temp.png')")
  (ess-execute ess-command)
  (ess-execute "dev.off()")
  (w3m-goto-url "file:///tmp/temp.png")
  (delete-other-windows))


Here's an example of running R-plot-w3m when the cursor in the R buffer
is on a line that contains: plot(1:10)
