Re: Babel should not work in the subtree marked as not exported

I wanted to try and reproduce this, as I thought I had the *opposite*
issue previously. I was correct, granted it was on Org < 8.0:
- http://lists.gnu.org/archive/html/emacs-orgmode/2012-10/msg00762.html

Code in :noexport: sections was not running, and I wanted to know how
I could get it to run (and I even had a :session argument). I took a
stab at your document with R and can't reproduce (behavior is the same
as in my post above). /However/, I get the same with you using ditaa,
even with no :session argument. Test file:

* Trying with R
Uses no =:session= argument; =R-yes.png= should be be created and
=R-no.png= should not.

** Don't run this   :noexport:

#+header: :file ./R-no.png :height 200
#+begin_src R :results output graphics

x <- 1:10
y <- x^2
plot(x,y)

#+end_src

** Run this

#+header: :file ./R-yes.png :height 200
#+begin_src R :results output graphics :exports results

x <- 1:10
y <- x^2
plot(x,y)

#+end_src
* Trying with ditaa

Uses no =:session= argument; =ditaa-yes.png= should be be created and
=ditaa-no.png= should not.

** Don't run this   :noexport:

#+BEGIN_SRC ditaa :file ./ditaa-no.png :cmdline -E
    +--------+---+---+---+---+---+---+---+  +---+---+---+---+---+---+---+---+
x   | 0 cRED | 0 | 0 | 0 | 0 | 0 | 0 | 0 |  | 0 | 0 | 0 | 0 | 1 | 0 | 1 | 1 |
    +--------+---+---+---+---+---+---+---+  +---+---+---+---+---+---+---+---+
#+END_SRC

** Run this

#+BEGIN_SRC ditaa :file ditaa-yes.png :cmdline -E
    +--------+---+---+---+---+---+---+---+  +---+---+---+---+---+---+---+---+
x   | 0 cRED | 0 | 0 | 0 | 0 | 0 | 0 | 0 |  | 0 | 0 | 0 | 0 | 1 | 0 | 1 | 1 |
    +--------+---+---+---+---+---+---+---+  +---+---+---+---+---+---+---+---+
#+END_SRC

And here's my minimal config:

;; change accordingly
(add-to-list 'load-path "~/.elisp/org.git/lisp/")
(add-to-list 'load-path "~/.elisp/org.git/contrib/lisp")
(add-to-list 'load-path "~/.elisp/site-lisp/ess/lisp/")

(require 'ox-latex)

(org-babel-do-load-languages
 'org-babel-load-languages
 '((R . t)
    (ditaa . t)))


So, I can reproduce, but the behavior is not the same with R. My
directory ends up with R-yes.png, and both ditaa-no.png *and*
ditaa-yes.png. Is there a way to track down the source of the
difference?
