I stumbled on this, too but hadn't posted back to the list yet. What
got me on the track to the solution was copying my babel block code
into an R source file and trying to do = > source("path/to/file")=
directly from R. That wasn't working either, so I knew it was
something I was doing and not org. I found the R faq which said that
source files don't generate output for everything unless you tell them
to print() :)

Thanks!
