Hi
Thierry Banel one of the authors of orgtbl-aggregate.el
Suggested to me the following code, if just want to extract one column
of a table.
#+TBLNAME: raw-data
| 1 | a | 3 |
| 2 | b | 4 |
| 3 | c | 6 |
| 4 | d | 7 |
#+BEGIN_SRC elisp :var data=raw-data
(mapcar (lambda (line)
(list (nth 2 line)))
data)
#+END_SRC
#+RESULTS:
| 3 |
| 4 |
| 6 |
| 7 |
It works nicely but how could I obtain the result with a table name,
like:
#+TBLNAME: RESULTS
| 3 |
| 4 |
| 6 |
| 7 |
Or something like this?
Thanks
Uwe Brauer

Thank you!
BTW I found it strange that the extracting function does not exist in
vanilla org.
My situation is a bit different, since I later want to use R.
So I have
#+TBLNAME: raw-data
| 1 | a | 3 |
| 2 | b | 4 |
| 3 | c | 6 |
| 4 | d | 7 |
#+NAME: NotasA
#+BEGIN_SRC elisp :var data=raw-data
(mapcar (lambda (line)
(list (nth 2 line)))
data)
#+END_SRC
#+RESULTS: NotasA
| 3 |
| 4 |
| 6 |
| 7 |
#+begin_src R :var notasA=notasA
summary(notasA)
#+end_src
And the last call does not work. It seems that R needs a table name.....

You may like the out-of-the-boxtable remote references:
| 3 |
| 4 |
| 6 |
| 7 |

#+TBLFM: $1=remote(raw-data,@@#$3)
The downside is that you need to create an empty table with the right
size before filling it with C-u C-c *

I get a result. Maybe you used downcase "notasA" where uppercase
"NotasA" was expected?
#+begin_src R :var notasA=NotasA
summary(notasA)
#+end_src
#+RESULTS:
| Min. :3.00 |
| 1st Qu.:3.75 |
| Median :5.00 |
| Mean :5.00 |
| 3rd Qu.:6.25 |
| Max. :7.00 |
