Re: [O] how do scientists use org mode?

[Christopher W. Ryan]

Just tried a similar thing on my computer at work: WinXP, emacs-22.3.1,
org-mode 7.7.  I tried both R and python.  With this in my .emacs file:

;; active Babel languages
(org-babel-do-load-languages
 'org-babel-load-languages
 '((R . t)
   (python . t)
   ))

Here are the contents of the org file I am playing with:

#+begin_src R
rnorm(10)
#+end_src

#+begin_src python
print "Hello, World!"
#+end_src


C-c C-c the first block results in a message like this:

Evaluate this R code block on your system? (yes or no)

Answering yes yields:

No org-babel-execute function for R!

Trying the same in the python block yields the same results, except with
"python" substituted for "R" in all the messages.

Any suggestions where I am going wrong?

Thanks.
