Hi,
I'm having some trouble getting ":cache yes" to behave the way I think
it's supposed to. As a test, I have a simple example containing just a
title and one source block:
#+source: testcache
#+begin_src R :cache yes :exports both :results output
dat <- matrix(runif(12), 3, 4)
print(dat)
#+end_src
If I export this document to HTML (C-c C-e b), Emacs asks me "Evaluate
this R code block (testcache) on your system?" If I say 'y' it
re-evaluates, if I say 'n' it doesn't, so it doesn't seem like there's any
role that caching gets to play here.
In addition, when I export the document as above, the results are not
saved in the original org-mode buffer, so whatever "#+results" block is
there (or not there) from doing C-c C-c is neither used nor overwritten -
and therefore the exported document contains different results than the
source document.
The behavior I expected (please let me know if my expectation is
incorrect) was for the result of the computation to be cached in the Emacs
buffer when I do the first export, and for that saved result to be
included in the exported content for subsequent exports, until either the
code/inputs change or I delete the results block.
My configuration is:
Emacs : GNU Emacs 23.2.50.1 (i386-apple-darwin9.8.0, NS
apple-appkit-949.54)
of 2010-08-18 on braeburn.aquamacs.org - Aquamacs Distribution 2.1
Package: Org-mode version 7.5
Thanks!

Hi Ken,
In order for caching to work, the results of the code block must exist
in the org-mode file. For example, the following code block will be
evaluated when triggered either interactively or during export
#+begin_src emacs-lisp :cache yes
(+ 2 2)
#+end_src
alternately, this block will not be evaluated when triggered either
interactively or on export, because the cached results are present
#+begin_src emacs-lisp :cache yes
(+ 2 2)
#+end_src
#+results[9b77429d6cea71daf37e21ee09170810b9905066]:
: 4
In your example, for the code block to not be evaluated as part of the
export process, you must first evaluate it manually within the Org-mode
file, leaving the results (with the hash tag) saved in the Org-mode
file.

I will chime in here, because I had a similar problem.
This does not work for me. When I evaluate manually (C-c c) I get the following:
* test
#+source: testcache
#+begin_src R :cache yes :exports both :results output
dat <- matrix(runif(12), 3, 4)
print(dat)
#+end_src
#+results[cad298135e53df633545d6a32a8b2aab5201721c]: testcache
: [,1] [,2] [,3] [,4]
: [1,] 0.4470891 0.2016197 0.1383083 0.6214485
: [2,] 0.1598936 0.3819967 0.3527698 0.5124687
: [3,] 0.3040325 0.5906898 0.1611272 0.1702849
Which I saved (just to be save).
When exporting to a pdf, I get the following matrix in the pdf:
[,1] [,2] [,3] [,4]
[1,] 0.5626863 0.8397120 0.9886886 0.2233873
[2,] 0.8697064 0.1101432 0.1372992 0.4114674
[3,] 0.3548678 0.5658843 0.1608864 0.5809167
And it is different after each export. So it seems that the code block
*is* actually evaluated, despite of the cached info.

Yes, that's exactly the behavior I'm seeing too. Caching seems to have no
effect on HTML export, no matter whether the block already has a
"#+results" section or not.

Thanks for pointing this out, your example doesn't work for me either.
I tracked this down to a problem of not finding the cached results of
named code blocks. I've just pushed up a simple fix for this issue, so
caching should now work as expected.

Thanks Eric. In my case I'm seeing the [mis]behavior even when the code
block has no name - will your fix cover that case too?

Actually, I just realized I'm mistaken. If I manually evaluate a
(non-named) block, *then* export the entire document, I indeed get the
cached results in the export, as expected.
However, if I change the code of a :cached block somewhere in my document
(or its MD5 is otherwise invalidated) and re-export the document without
first doing C-c C-c, the export will neither use the cache (which is good)
nor save the results back to the cache (which is bad), so the export is
now out of sync with the original. It would be great if the results in
exports could be cached in the same way they would be cached when manually
evaluating blocks.
Or perhaps, is there some command to evaluate all blocks in a document
that need to be re-evaluated, and save the results back to the buffer? I
could do that every time before exporting, maybe.

One of the features of Org-mode export is that the document is not
changed by the act of exporting, so unfortunately you will have to
manually evaluate all code blocks, and save their results before
exporting.

Fortunately there is such a function, org-babel-execute-buffer, bound to
C-c C-v b, try C-c C-v h in an Org-mode buffer to see all code block
specific key bindings.

So I tried doing that, and unfortunately it looks like I'm going to have
to restructure my document a bit if I want to use it. I'd been using
"#+begin_src" blocks in two different ways - some blocks are just "code
listings" that I don't really intend to run, whereas some blocks are "live
code" that I want to execute when exporting the document - these latter
have Babel-style arguments like ":exports both" or ":results output" and
the like.
Of course, "C-c C-v b" will treat *all* of the blocks like "live code"
blocks, so I'm looking for some way to shut off Babel processing of many
of the blocks and just treat them as styled code listings. Is there some
flag to do that, or should I switch from "#+BEGIN_SRC sh" to
"#+BEGIN_EXAMPLE sh" or something? Does BEGIN_EXAMPLE know about
different languages of code?

Try :eval never
http://orgmode.org/org.html#eval
Don't know if that will work, but it sounds promising.
