Austin, could you point us to the tools you plan to use for code weaving?

I agree, this sounds great. I was just about to start trying to combine org and latex usage in any case. However I'm being dense. I've done git pull && make && make install, and I have org-version equal to 6.04b. OK so far, right? Now I create an org file containing

* section 1
  #+BEGIN_SRC latex
  \log p(z|x,\theta)
  #+END_SRC
* section 2
  #+BEGIN_SRC r
  xor <- function(a,b) (a | b) & !(a & b)
  #+END_SRC
* section 3
  #+BEGIN_SRC emacs-lisp
  (defun org-xor (a b)
  "Exclusive or."
  (if a (not b) b))
  #+END_SRC

but despite repeated invocations of /C-c '/ and org-edit-special and org-edit-src-example, with point in various places, I haven't brought up a narrowed buffer in the requested mode. Instead I get 
C-c ' can do nothing useful here. (from C-c ' and org-edit-special) and silence from org-edit-src-example

I'm sure I'm being stupid, could someone tell me how?

I'm also a heavy R user, so I liked Austin's suggestion of combining org with Sweave / Rnw files and look forward to further developments. I might have a go myself if I can get beyond step 1 here. Sweave/Rnw files can get really ugly and cumbersome and merely org-style outlining and folding would be excellent, though I bet it can go much further than that. Austin -- it would be well worth CC'ing any developments on that front to the ESS (Emacs Speaks Statistics) mailing list.

See http://www.r-project.org and http://www.statistik.lmu.de/~leisch/Sweave/. Sweave() is an R function that processes an R/noweb file containing a mixture of R and latex, evaluating the R code and inlining any resulting textual or graphical output into the latex output.

The #+begin and #+end lines must start in column 0,
you have whitespace in front of them.

If you load the org-mtags.el module, you can also use
a Muse-like syntax:

   <src lang="latex">


   </src>

these may be indented.

Re: Emacs-orgmode Digest, Vol 27, Issue 47

Okay, got one little problem report here:

Loading org...done
Problems while trying to load feature `org-id'
Loading disp-table...done
Loading edmacro...done
Loading footnote...done
Loading vc-svn...done
Loading vc...done
Loading cl-seq...done


Let me just mention that if the "Problems" report gave some clue as to
what the problem was, it would be easier to help debug it.  But in any
case, this I do't think is a feature I'm using yet.

Hi Charles, this report meant that a

  (require 'org-id)

has failed.  Cannot imagine why.
