That wasn't a very good description, sorry. ...... I just wrote a detailed description of the bug, and then remembered that I forgot to copy the latest org pull into /usr/share/emacs/24/lisp/org. This bug is now gone, probably as a result of you fixing export evaluation order. However, the description of "replace results" bug is still relevant. I'll denote issues that are now fixed with appropriate markup. #+BEGIN_MOOT_POINT Take test-export4.org from my original message, and export (C-c C-e h; don't evaluate the buffer beforehand). You will see the following output: http://i.imgur.com/IM3oy.png There are two problems: (1) Notice that the output of _every_ src_R block is "images/conv2.png" It should be "conv1.png" on the first invocation "conv2.png" on the second, and "conv3.png" on the third. (2) The last src_R block is not evaluated and, in fact, appears in the output (which it shouldn't), mangled, as the underscore is taken as a subscript. #+END_MOOT_POINT For comparison, if you first evaluate the buffer, and then export, you will see this: http://i.imgur.com/V6PXq.png The output of the src_R blocks is now correct, but I don't see why one needs to pre-evaluate the buffer to get correct output on export. The overall output, as you can see, is _not_ correct, since the results from invocation of src_R blocks via the export are _appended_ to those that were generated via C-c C-v b. > > Could you isolate a minimal example demonstrating just the failure of > results replacement? Run the below code a few times with C-c C-v b, and you'll see ------------snip--------- #+property: session *R-babel* #+NAME: foo #+HEADER: :var plot.filename="conv1.png" #+BEGIN_SRC R :results output silent cat.fname.link <- function() { cat(plot.filename,"\n",sep="") } cat.fname.link() #+END_SRC src_R[:results output replace]{ cat.fname.link() } ------------snip--------- You can also replace src_R with #+begin_src R :results output raw replace :exports results cat.fname.link() #+end_src and it will also fail to replace results. All the above examples were run with the latest pull of org. HTH, --Leo
