[ESS] Can not interrupt long printing

[Ponting, Keith (Keith)]

I too have the same issue from time to time.  My .emacs now contains:

(defun my-ess-post-run-hook ()
  (ess-execute-screen-options) ; see ESS-help Digest vol 77 issue 10
  (local-set-key "\C-cw" 'ess-execute-screen-options)
  (if (string= ess-dialect "R") (ess-eval-linewise "options(max.print=100)" nil nil nil (quote wait)))
)
(add-hook 'ess-post-run-hook 'my-ess-post-run-hook)

For completeness of information, I am using Vincent Goulet's excellent pre-bundled Emacs (24.1 modified 1) for Windows. The start of an R session now looks like:
...
> > options(chmhelp = FALSE, help_type = "text")
> options(width=152,length=99999)
> options(max.print=100)
> assignInNamespace(".help.ESS",help, ns = asNamespace("base"))
> options(STERM='iESS', str.dendrogram.last ="'", editor='gnuclient.exe')

The width/length options come from ess-execute-screen-options to match current width
of Emacs window; the max.print from my code above.
I am not altogether sure where the other options and assign come from.  

HTH,

Keith
