Problem whit with code evaluation

["Blanchette, Marco" <MAB@stowers.org>]

Sorry again if this is common knowledge, but the road to orgmode power user
is seeded with challenges!

I am trying to write an R function that would take 3 arguments, hopefully
set up in an org table and have a function run every rows, taking every
column as arguments to produce a set of report files... But I am going a bit
ahead of myself as I am stuck quite early in the development...

My problem is quite basic. For some reason, I can¹t seems to be able to
execute the following lines in the org buffer using org-babel-execute-buffer
or to export an html of the files. The code block just don't execute and
return errors.

* Examples take from
[[http://orgmode.org/worg/org-contrib/babel/intro.php#sec-7]]

* The python example
#+source: square(x)
#+begin_src python
x*x
#+end_src

#+call: square(x=6)

* The elisp example of the fibonacci series using a table as argument

#+tblname: fibonacci-inputs
| 1 | 2 | 3 | 4 |  5 |  6 |  7 |  8 |  9 | 10 |
| 2 | 4 | 6 | 8 | 10 | 12 | 14 | 16 | 18 | 20 |

#+srcname: fibonacci-seq(fib-inputs=fibonacci-inputs)
#+begin_src emacs-lisp
  (defun fibonacci (n)
    (if (or (= n 0) (= n 1))
        n
      (+ (fibonacci (- n 1)) (fibonacci (- n 2)))))
  
  (mapcar (lambda (row)
            (mapcar #'fibonacci row)) fib-inputs)
#+end_src

* Then my own trial in R
#+srcname: test(x y)
#+begin_src R
   p <- x*y
#+end_src

#+call test(x=4 y=9)
#+function test(x=3 y=8)

Is there something I am missing?

My current setup is:
GNU Emacs 23.1.50.1
org-mode (v7.01g)
R v2.11.1
XServer running Snow Leopard Server 10.6.4

Thanks for the help
