Hi I am trying to export the attached test.org file to HTML, but I can only export it, when I change the source block language to anything different from R. I also attach my emacs.org file, but I am not doing any customisations to R. In addition: if I specify :session *R* in #:BABEL: , the code is evaluated, even though I specified :exports code. Is this intended? Thanks, Rainer -- NEW GERMAN FAX NUMBER!!! Rainer M. Krug, PhD (Conservation Ecology, SUN), MSc (Conservation Biology, UCT), Dipl. Phys.
