You are right!! I did not pay attention!

Now it works, thanks very very much, that simplifies my workflow.

Thank you!

BTW I found it strange that the extracting function does not exist in
vanilla org.

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 *




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.

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 |

| Max.   :7.00 |

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=""
(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 






You may name the Lisp block like that:
  
  --

#+TBLNAME: raw-data
| 1 | a | 3 |
| 2 | b | 4 |
| 3 | c | 6 |
| 4 | d | 7 |

#+NAME: just-one-column
#+BEGIN_SRC elisp :var data="">
(mapcar (lambda (line)
    (list (nth 2 line)))
 data)
#+END_SRC

#+RESULTS: just-one-column
| 3 |
| 4 |
| 6 |
| 7 |
  
--


  Then you can use the new table in a further processing:

--

#+BEGIN_SRC elisp :var data="">
(mapcar (lambda (line)
  (list (* 1000 (nth 0 line
 data)
#+END_SRC

#+RESULTS:
| 3000 |
| 4000 |
| 6000 |
| 7000 |

--
