Re: What determines if R source block output is wrapped in begin_example or not?

[John Hendy]

Possible false alarm. As I continued to work on this, I accidentally
didn't use :results output code, yet the formatting was fine... I'm
wondering if I had a dangling #+begin_src with no matching end?

Still, I am intrigued by the toggle between prepending with ":" and
wrapping in example blocks, despite what appears to be no practical
impact at this point.
