The following works
#+name: xvar
#+begin_src emacs-lisp
"ahaRx"
#+end_src
#+RESULTS: xvar
: ahaR
#+name: myblock
#+begin_src R :var xxx=xvar
xxx
#+end_src
#+RESULTS: myblock
: ahaRx
But when I replace emacs-lisp with R in the first code block, it does not work any more.
I think it should because R also returns the character value in that case.
Any ideas?

Why are you not using something that you know works? Try the following
for example.
#+name: xvar
|"ahaRx"|
#+name: myblock
#+begin_src R :var xxx=xvar
xxx
#+end_src
#+RESULTS: myblock
: ahaRx
As I understand it, Babel can read from tables and lists only.
Actually, to me, reading from a block of text doesn't make much sense
for a source block. What kind of data structure would it represent
(other than a long string of course :-p)?

Open source is the future. It sets us free.

This works here:
#+name: xvar
#+begin_src R
"ahaRx"
#+end_src
#+RESULTS: xvar
: ahaRx
#+name: myblock
#+begin_src R :var xxx=xvar
xxx
#+end_src
#+RESULTS: myblock
: ahaRx
You don't say what doesn't work, which makes it difficult to diagnose
what might be going wrong on your end.
All the best,
Tom

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.
