Outshine is like Org, no enclosing, but file structuring with
(outcommented) headlines.

I'm not sure if I understand. When you use ob-R.el, you work in Org
files with R source blocks, right? When do you want to fold the R output
below? When you are in org-mode or when editing source blocks in R-mode?

In the former case, Org-mode is in charge and you don't need
outshine. In the latter case, you could install outshine as described in
the docs and then add outline-minor-mode to the ESS/R mode hook, i.e.

,-------------------------------------------------------------------------------
| ;; outline
| (when (require 'outline nil t)
|  (add-hook 'ess-mode-hook 'outline-minor-mode)) ; is that the hook for R-mode?
| 
| ;; outshine
| (when (require 'outshine nil t)
|  (add-hook 'outline-minor-mode-hook 'outshine-hook-function)
|  (setq outshine-use-speed-commands t))
`-------------------------------------------------------------------------------

Outshine headlines are outcommented Org headlines, i.e. 

,----------------------------------
| * Beginning org variable transfer
`----------------------------------

becomes 

,----------
| ## * Beginning org variable transfer
`----------

in R-mode. 

The R output would become an outshine-subtree with the header above,
just like in Org-mode, possibly surrounded by other subtrees.
