Yep, using a couple of for loops will work but the result won't return
as a
table which is a requirement for me.
To precise the context a littre more, I have basically 2 source blocks :
1) the famous python block which must return a table
2) a R block used to post-process the previous table
Well, thanks for your help.
I think I spent too much time on this so I'm thinking about changing my
approach. For example, put the result of the first step into a file and
then
process the file in step 2.
Best regards,
Roland.
Just playing a little bit with your example, what about this:
#+begin_src python :results output :preamble # -*- coding: utf-8 -*-
a = ( ( é, a ), ( a, à ) )
for i, j in a:
print(|%s | %s| % (i, j))
#+end_src
Yes Andreas! It works just fine for the python block. But when the python
result arrives as input of my R post
processing code, R receives the following string | é | a |\n| a | à |\n
whereas a data.frame is
expected. Indeed, theoretically, when a org-table is used as input of a R
source block, the
org-table is automatically converted into a data.frame which is very
convenient to handle data.
Here is my buffer :
#+name: pytab
#+begin_src python :results output raw :preamble # -*- coding: utf-8 -*-
a = ( ( é, a ), ( a, à ) )
for i, j in a:
print | {0} | {1} |.format( i, j )
#+end_src
#+TBLNAME: pytab
| é | a |
| a | à |
#+name: Rpostproc
#+begin_src R :results output :session :preamble # -*- coding: utf-8 -*-
:var tab=pytab
print( tab )
#+end_src
#+RESULTS: Rpostproc
: [1] | é | a |\n| a | à |\n
In fact, converting the results of my python block into a string looking
like an org-table is what I
used to do before I had to use a R block to post process results.
I assume that org-babel asks for a re-evaluation of pytab source block
when pytab is used as argument of another source block.
The problem stems from the fact that it's the direct evaluation of pytab
(a string) which is used and
not the org-table converted result as shown in the buffer.
Well, I could just convert the R string into a data.frame but it's very
complete with my real data
(non trivial separator problems).
A solution to this problem could be to force org-babel to take as argument
of the R code what is
really shown in the buffer and not the direct result of the python block.
Another solution could be
to stop the re-evaluation of the R arguments.
Anyway, thanks to spend time on this Andreas!

The bug so far affected the display only, not the data. Feeding R with the result returned from your original form should work. Best, Andreas Ah you're right It's a bit annoying to enter the encoding when Emacs asks for it but it works on the previous example. It's not the case with my real data but it's another problem to solve now ;). Thanks a lot for your help Best regards Roland.

hmm, indeed, shows up nicely now. Please close, cheers, Andreas That's right, it works with python3 but that is not the case with python2... Cheers, Roland.
