Hi,

I encountered the following problem using org-mode with R code blocks. 
When using #PROPERTY: var in my org file to set global variables, R 
stops to recognize the column names of org tables defined like this:

#+TBLNAME: parameters-xlinked
| A | B |
|---+---|
| 1 | 2 |

#+begin_src R :session :var par.xlinked=parameters-xlinked :results 
output org
    ascii(par.xlinked)
#+end_src

#+RESULTS:
#+BEGIN_ORG
  |   | V1   | V2   |
|---+------+------|
| 1 | 1.00 | 2.00 |
#+END_ORG


without the variable defined I get the correct header:

#+RESULTS:
#+BEGIN_ORG
  |   | A    | B    |
|---+------+------|
| 1 | 1.00 | 2.00 |
#+END_ORG


So, somehow setting the variable property messes with the variable 
interface to R.
