No problem.

So everything after the outcommented headline will be folded - so if I
only want to fold one part, I have to use

,----
| ## * If this is folded
|  SOME R CODE
| ## * This not anymore
|  SOME R CODE
`----

which I could fold to

,----
| ## * If this is folded [...]
| ## * This not anymore
|  SOME R CODE
`----

correct?

Correct.

The evaluated code - not in the source code.

True.

That's it.

Sounds great - thanks a lot. I will try it out,
