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 |

You are right!! I did not pay attention!

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