I know. That is why I said it is a 'start'. You can work around this
with more Babel if that is the only issue. Write a src block `good-fmt'
that will render the body of another block as you want it and then use
<<good-fmt("R-src-blk-with-quotes")>> to insert it.

See Aaron Ecay's patches from around 08/2014. And discussions on this
list from about that time. He had some of this working, but there
were some issues about handling remote calls, IIRC.

By default knitr interlaces the code and output in a frame with
the output lines prefixed by '##'. The code is highlighted by default.
In *.Rnw this leads to a single block with a background color and
colorized code.
In *.Rhtml you get source code blocks colored per <div class="source">
and results blocks uncolored per <div class="output">.
Using *.org via ox-ravel --> *.Rhtml via knitr --> *.html will get you
that far.
Maybe customizing the classes to your taste will finish it.
Best,
Chuck
p.s. If you go with ox-ravel, I recommend the ravel-lang branch:
