Dear Experts,
I think org-babel is awesome but I'm having some trouble chaining
together multiple function calls.
Specifically, I would like to do something like the following
#+tblname: fancier
| mean |
|--------|
| #ERROR |
#+TBLFM: @2$1='(sbe "python-mean" (x (sbe "tbl-example-data" (seed 4) (size
(sbe "square" (x 4))))))
but it doesn't work.
Can someone help me understand:
1. How to make this work?
2. How to debug things like this (e.g., how do I make something
appearing in a table get its own session so I can use
org-babel-pop-to-session)?
Supporting code and building up examples to try to make the above work
are shown below.
The following builds up examples for multiple function calls. Save
this in org-mode and see what happens.
Create a block to generate random data:
#+srcname: tbl-example-data(seed=2, size=3)
#+begin_src python :
import random
random.seed(seed)
return [i+random.gauss(0,.1) for i in range(size)]
#+end_src
Create a block to compute the mean
#+srcname: python-mean(x)
#+begin_src python
return sum(x)/float(len(x))
#+end_src
Create a table to use the data. To update the table do "C-u C-c *" in
the table.
#+tblname: summaries
| mean |
|---------------|
| 1.06900574831 |
#+TBLFM: @2$1='(sbe "python-mean" (x "tbl-example-data"))
Create a table to use the data where we pass arguments to
tbl-example-data. To update the table do "C-u C-c *" in the table.
#+tblname: fancy
| mean |
|---------------|
| 3.53014887192 |
#+TBLFM: @2$1='(sbe "python-mean" (x "tbl-example-data(seed=4,size=8)"))
Define a square function:
#+srcname: square(x)
#+begin_src python
return x*x
#+end_src
Test squaring:
#+tblname: testSquaring
| mean |
|------|
| 16 |
#+TBLFM: @2$1='(sbe "square" (x 4))
Try to do something even fancier and it doesn't work:
#+tblname: fancier
| mean |
|------|
| |
#+TBLFM: @2$1='(sbe "python-mean" (x
"tbl-example-data(seed=4,size=square(4))"))
Try to do something even fancier with sbe and it doesn't work.
#+tblname: fancier
| mean |
|------|
| |
#+TBLFM: @2$1='(sbe "python-mean" (x (sbe "tbl-example-data" (seed 4) (size
square(4)))))
One more try:
#+tblname: fancier
| mean |
|--------|
| #ERROR |
#+TBLFM: @2$1='(sbe "python-mean" (x (sbe "tbl-example-data" (seed 4) (size
(sbe "square" (x 4))))))
