I'm fine with whatever, though I think ob-R-doc is in need of a
refresher, since I don't particularly think raw vs. org (and now wrap,
which is non-existent in formal documentation from what I've seen) is
explained extremely well. I'd be happy to help, but I don't understand
the differences myself.

For example, in our previous discussion (from the thread linked in my
original post), it seems like raw was the /gist/ of what I wanted, but
raw didn't know how to replace org-specific syntax [[filename]]
properly, so I needed org.

I also can't find any references to =output wrap=. Tried googling
=output wrap R orgmode babel= and then ="output wrap" R orgmode babel=
to try to find some discussions on this.


Thanks for letting me know,
John
