Hi

shouldn't the following not give an error from R as it should not be
expanding the variables?

--8<---------------cut here---------------start------------->8---
#+PROPERTY: no-expand TRUE
#+PROPERTY: var YEAR=2014

* a noexpand code

#+begin_src R :results output :no-expand
cat(YEAR)
#+end_src

#+RESULTS:
: 2014
--8<---------------cut here---------------end--------------->8---

The manual states:

,----
| 14.8.2.11 `:no-expand'
| ......................
| 
| By default, code blocks are expanded with `org-babel-expand-src-block'
| during tangling.  This has the effect of assigning values to variables
| specified with `:var' (see *Note var::), and of replacing "noweb"
| references (see *Note Noweb reference syntax::) with their targets.  The
| `:no-expand' header argument can be used to turn off this behavior.
`----

Org-mode version 8.2.5h (release_8.2.5h-869-gdcfe09 @
/Users/rainerkrug/.emacs.d/org-mode/lisp/)

Cheers,

Rainer

I guess this should be:

  #+PROPERTY: no-expand yes

Nope - the same.

According to the manual :no-expand is only supposed to have an effect
during tangling, not execution.

Best,

Thanks Eric - re-reading the manual, it became clear. Maybe to clarify
this in the manual, one could say:

,----
| The `:no-expand' header argument can be used to turn off this behavior
| for tangling and has no effect on the expansion during code execution.
`----

instead of:

,----
| The `:no-expand' header argument can be used to turn off this behavior.

Could you supply a patch?

Sorry to ask for such a trivial thing, but I'm *very* short on time
these days, and applying a patch is *much* easier.

Thanks,

Sure - should have done it instead of asking.
