With the :session arg I get the output as you show it below.

This was with master on commit f79545 from last month and on today's master (commit 38a8901).

FWIW, my R session looks like this


--8<---------------cut here---------------start------------->8---

Type 'demo()' for some demos, 'help()' for on-line help, or
'help.start()' for an HTML browser interface to help.
Type 'q()' to quit R.

If this is what your session looks like, then we need to dig deeper into ob-R.
