Greetings. I've been having problems lately in exporting Org-Mode source-code
documents to HTML and/or PDF.
I'm running Org-Mode 7.7 with Emacs 23 on 64-bit linux (Fedora 15).
I've appended a document that exhibits at least some of the problem. The
problems are similar to the problem described at:
http://comments.gmane.org/gmane.emacs.orgmode/45316
and can *sometimes* be circumvented by executing org-reload.
In the particular example shown below, the HTML export works as expected, but
the PDF export fails with message:
org-export-latex-preprocess: Wrong type argument: stringp, nil
By the way, everything worked fine in the
example until I added the last
source block:
#+begin_src
R
x
#+end_src
I tried using what I take to be the latest version of Org-Mode:
Org-mode version 7.7 (release_7.7.290.g65d05)
but that only made things worse. I tried an HTML export with this version, and
it generated a horrendous-looking message that begins with:
org-babel-R-evaluate: Wrong number of arguments: #[(session body result-type
result-params column-names-p row-names-p) Æ=}...
followed by a bunch of stuff containing enough non-printing characters that
it's hard to reproduce in email, and ending with:
...org-mode/lisp/ob-R.elc" . 9734)], 5
I'd welcome any help/advice that anybody can provide.
Thanks,
-- Mike
########## Sample file that exhibits some export problems

:session *R* :cache yes :results output graphics :exports both :tangle yes
* Getting Started
** Batch Mode
#+begin_src R :exports code
pdf("xh.pdf") # set graphical output file
hist(rnorm(100)) # generate 100 N(0,1) variates and plot their histogram
dev.off() # close the graphical output file

If we put the code above in a file called =z.R=, we can execute the
code from the command line via: =R CMD BATCH z.R=
#+begin_src R
