I am not sure whether I am able to actively contribute (either to R-core
or to ESS) on a permanent basis.
The purpose of my request was that I wanted suggest a small addition to
ESS.

For debugging purposes I often want to run my R code from the beginning
of the buffer until the current position. That is why I added a small
function, based on the function ess-eval-buffer (starting on line 1159
in file ess-inf.el, ess-version 5.12).

I modified it a bit that it does not evaluate from (point-min) to
(point-max) but only to (point) -- see below.

(defun ess-eval-buffer-from-start-til-here (vis)
  (interactive "P")
  (ess-eval-region (point-min) (point) vis "Eval buffer from start til
here"))

I'd be happy if you think it is worthwhile to include it in ESS.
Furthermore, I added some keybindings.
I put into my .emacs file:
(global-set-key (kbd "C-c C-<up>") 'ess-eval-buffer-from-start-til-here)

I guess, however, that it is better not to set any keys globally as a
general solution. That is why I would suggest to add

(define-key ess-mode-map (kbd "C-c C-<up>")
'ess-eval-buffer-from-start-til-here)

to the keybinding definitions in ess-mode.el

Thank you very much,
Roland
