Re: :var problems with R

[Neuwirth Erich <erich.neuwirth@univie.ac.at>]

Meanwhile I learned that

#+name: xvar
: waterfall

#+name: myblock
#+begin_src R :var xxx=xvar
print(xxx)
#+end_src

#+RESULTS: myblock
: waterfall


ans so will

#+name: xvar2
: water

#+name: myblock2
#+begin_src R :var xxx=xvar2
xxx
#+end_src

#+RESULTS: myblock2
: water

The critical missing piece for me was the colon in front of the value in a name definition.

I wanted this because I am running a project on different machines, and I want to give the
name od subdirectories through this mechanism.
Ir seems cleaner than using code in a programming language when we just need constants.


And I explained the problem seems to be that a value returned by R in a named block is not accessible
as a named "variable".
In this case, I would rather stay with R which I need anyhow and I have to explain to my coworkers.
Using emacs-lisp additionally would just make things harder to understand fore some of the project members.



This also works now

#+name: rvar
#+begin_src R
"raha"
#+end_src

#+RESULTS: rvar
: raha

#+name: rvartest
#+begin_src R :var xxx=rvar
xxx
#+end_src


I had misunderstood something there.
