John and Nick-- The question about whether I have python on my machine is not silly--I am. Got so carried away I forgot I was on my work computer, which indeed does not have python. But I do have R and perl, and similar code blocks in either language yield the same problem, so I'll just focus on them as examples (he said, sheepishly.)
I usually interface with R via emacs ESS. Currently ESS is using R version 2.11.1. R executable is in C:\Program Files\R\R-2.11.1\bin I usually interface with perl via another text editor, Programmer's Notepad, set up with drop-down menu item to execute the file in perl. Perl executable is in C:\strawberry\perl\bin C:\Org\org-7.7\lisp contains, among others, files called ob-R.el and ob-perl.el Currently my path variable looks like this: Files\QuickTime\QTSystem\;C:\WINDOWS\system32\WindowsPowerShell\v1.0;C:\Xpdf;C:\strawberry\perl\bin;C:\strawberry\c\bin;C:\strawberry\perl\site\bin My .emacs now contains: ;; active Babel languages (org-babel-do-load-languages 'org-babel-load-languages '((R . t) (python . t) (perl . t) )) As to Nick's questions, M-x locate-library RET ob-R RET tells me ob-R is located in C:\Org\org-7.7\lisp\ob-R.el M-: to evaluate (require 'ob-R.el) yields ob-R in the minibuffer Then C-c C-c in the R code block yields Code block produced not output. in the minibuffer, and a new buffer that says, 'R' is not recognized as an internal or external command, operable program or batch file. I tried evaluating (require 'ob-perl) and this yielded ob-perl in the minibuffer, and thereafter the perl code block executed properly. I wonder if I need to put the path to R in my PATH variable? (come to think of it, don't know why it's not already there); its absence has so far not prevented me from using R via ESS. Thanks. --Chris Christopher W.
