simple variables as arguments to source block

simple variables as arguments to source block

[Andreas Leha]

Hi all,

I'd like to pass a string to a source block -- not directly, though, but
through a reference.  What is the recommended way to do this?

This is what I gather from the manual:

--8<---------------cut here---------------start------------->8---
#+name: myvar
| aaa |


#+begin_src R test :var myvar=myvar[0,0]
  print(myvar)
#+end_src
--8<---------------cut here---------------end--------------->8---


My question is: How can I get rid of the [0,0]?

Regards,
Andreas

How about:

#+BEGIN_SRC Org
#+NAME: myvar
: 4

#+BEGIN_SRC R :var x=myvar
x
#+END_SRC

#+RESULTS:
: 4
#+END_SRC 

-- 
This is the kind of tedious nonsense up with which I will not put

Works, indeed.  Thanks.
