I've just started up a minimal Emacs instance and loaded the babel
portion of your attached config, but I am able to export your attached
org file w/o error.  A couple of questions.

1) are you able to export to latex?  If so, then maybe the issue has to
   do with fontification of R code by htmlize-buffer

2) could you send in the actual error being reported by Emacs, or a
   stack trace?

Yes, this is for Sweave like behavior.

If you have a session specified for every block in the buffer, and you
are exporting the buffer, there are cases when you need a block to be
executed (e.g. because it sets the value of a variable used by a
subsequent block) even though you *do not* want the results of the block
included in the final document.  To support these use cases, on export
every block with a session is executed so that it's effects on the
persist session takes place.

Cheers -- Eric
