Hi,

Am I mistaken or is it not possible to combine :colnames and :post?
Here's an example of what I have got in mind:

--8<---------------cut here---------------start------------->8---
#+NAME: identity
#+BEGIN_SRC emacs-lisp :var x="x"
x
#+END_SRC

#+BEGIN_SRC R :colnames yes :post identity(*this*)
setNames(data.frame(1:2), "foo")
#+END_SRC

#+RESULTS:
| 1 |
| 2 |

Expected result:

| foo |
|-----|
|   1 |
|   2 |
--8<---------------cut here---------------end--------------->8---

Thanks,
Rasmus

  Hi Rasmus,
  
  You also have to add :colnames to the :post header:
  
  :post identity[:colnames yes](*this*)
  
  Another option is to add :colnames yes to the identity block itself:
  
  #+NAME: identity
  #+BEGIN_SRC emacs-lisp :var x="x" :colnames yes
    ...
  #+END_SRC

    Thanks Aaron.  That even makes sense in its own, quirky way!
    
    Should add a note on this to the manual?  Or is it clear enough as it is?

      Hi Rasmus,

      I think it would be a good idea to add a note about this in the manual.
      Perhaps in the form of another example in the node for the :post header
      argument (info "(org) post") which shows how to use :post to process a
      tabular result.
      
      Thanks,

        I'm a bit busy right now, but here's a quick proposal.  If you are happy
        with it, I'll push it.
