[ESS] R code folding with hideshow-org.el

[Vitalie S.]

There is 'hs-toggle-hiding function in hs that does almost the same thing. I am not sure that messing with tab indentation is such a good idea.

It would be extremely useful to have Org like tab-cycling for allout (a good outliner for code: http://www.emacswiki.org/emacs/AllOut),which would work just on headings. 

Does anyone know a way to do that?

Hideshowvis (http://www.emacswiki.org/emacs/hideshowvis.el) is a nifty extension to hideshow which adds -+ and colored rectangle to folded regions. 
I have this in my .emacs:

(autoload 'hideshowvis-enable "hideshowvis" "Highlight foldable regions")
(dolist (hook (list 'emacs-lisp-mode-hook
                    'ess-mode-hook))
  (add-hook hook 'hideshowvis-enable))
(setq hs-special-modes-alist
      (cons '(ess-mode "{" "}" "#" nil nil) hs-special-modes-alist))
