no, it should look just like a folded subtree in Org-mode. 
The problem is probably this

,--------------------------------------
| + . + ## * Variable Transfer from org
`--------------------------------------

because in outshine, just like in Org, a header must (!) start at the
beginning of line to be recognized. 

Or is the comment syntax wrong for R-mode? Is it only

,-------------
| # * Level 1
`-------------

? I can't check right now, you can try it out by writing an Org header in an
R buffer and then call M-x comment-region on the marked line. Maybe I
got confused because PicoLisp uses ## for comments ...
