Error with :wrap org in babel and 8.0-pre

[John Hendy <jw.hendy@gmail.com>]

I thought this was the proper syntax for printing stuff directly to a
LaTeX document:

#+begin_src R :session :exports results :results output :wrap org

I've got a statement interspersing some prose with variable values like so:

cat("This and such value was," var1, ", and this one was", var2, ".\n")

The results block looks fine, but LaTeX is spitting out \begin{org}
and \end{org} around it, which results in a compilation error:

! LaTeX Error: Environment org undefined.

See the LaTeX manual or LaTeX Companion for explanation.
Type  H <return>  for immediate help.
 ...

l.51 \begin{org}


! LaTeX Error: \begin{document} ended by \end{org}.

Suggestions?


Thanks,
John
