extract a region from a table and export it

extract a region from a table and export it

[Uwe Brauer]

Hi

Is it possible to extract just say two regions from a huge table and
convert it to say CSV?

Yes. Anything you can think of is possible in Emacs. Usually in two or
more different ways. :-)

Presumably you want to automate this to make it quickly repeatable.
Please show us some sample table rows and explain the criteria you
would want to use to identify which regions to extract.

Re: extract a region from a table and export it

[John Kitchin]

can you write a little code block that filters the table for what you
want, and then convert that to a pdf?

Something like:


#+tblname: data
| 1 | a |
| 2 | r |
| 5 | 7 |
| 4 | 9 |
| 8 | y |

#+BEGIN_SRC emacs-lisp :var d=data
(orgtbl-to-csv (-filter (lambda (x) (and (> (car x) 2) (< (car x) 8))) d) nil)
#+END_SRC

#+RESULTS:
: 5,7
: 4,9

or, rows 0, 1 and 4.

#+BEGIN_SRC emacs-lisp :var d=data
(loop for i in '(0 1 4) collect (elt d i))
#+END_SRC

#+RESULTS:
| 1 | a |
| 2 | r |
| 8 | y |

Great! Thanks a lot. This is a brilliant idea, on a second thought I
would even say that I don't need orgtbl-to-csv, but I just want to
extract 3 columns of a table which contains 10. What would the relevant
syntax be for column, please?

This way I have a poor-man's database (basically I need that for the
grades of my students).

I obtain an error when I run your code (but of them, namely)
(but I am using a very recent version of org mode)

Ok the second code works now, and is almost what I want, but I need it
mostly for columns, it is not obvious for me that corresponds in the
syntax above to columns.

[John Kitchin]

How about:

#+tblname: grades
|    | H1 | H2 | H3 |
|----+----+----+----|
| P1 | 90 | 89 | 91 |
| P2 | 67 | 65 | 78 |
| P3 | 99 | 98 | 97 |

collect row 0 and 2, columns 0 (P) and 2 (H2)


#+BEGIN_SRC emacs-lisp :var data=grades
(loop for i in '(0 2)
      with row = nil
      do
      (setq row (nth i data))
      collect (list (nth 0 row) (nth 2 row)))
#+END_SRC

#+RESULTS:
| P1 | 89 |
| P3 | 98 |

Great exactly what I needed, thanks!
Maybe such code should be included somewhere, (manual?)

See (info "(org) var") in particular the section on "Indexable variable
values".


        Additionally, an empty index, or the single character ‘*’, are both
     interpreted to mean the entire range and as such are equivalent to
     ‘0:-1’, as shown in the following example in which the entire first
     column is referenced.

          #+NAME: example-table
          | 1 | a |
          | 2 | b |
          | 3 | c |
          | 4 | d |

          #+BEGIN_SRC emacs-lisp :var data=example-table[,0]
            data

Thanks that looks like a very simple solution, however how can one
obtain the first column of the table in column format? (I know I could
transverse it, but just out of curiosity.

It is also not clear to me how you could extract say the first and the
third column from the following table

| 1 | a | 3 |
| 2 | b | 4 |
| 3 | c | 6 |
| 4 | d | 7 |

Using your approach?

Re: extract a region from a table and export it

[John Kitchin]

the problem seems to be that c0 and c2 are set to nil for some reason. I
doubt dash has anything to do with it. Try these:

#+BEGIN_SRC emacs-lisp :var c0=tab2[,0] :var c2=tab2[,2]
c0
#+END_SRC

#+RESULTS:
| 1 | 2 | 3 | 4 |

#+BEGIN_SRC emacs-lisp :var c0=tab2[,0] :var c2=tab2[,2]
c2
#+END_SRC

#+RESULTS:
| 3 | 4 | 6 | 7 |

Here is a non-dash solution that works for two lists.

#+BEGIN_SRC emacs-lisp :var c0=tab2[,0] :var c2=tab2[,2]
(loop for a in c0 for b in c2 collect (list a b))
#+END_SRC

#+RESULTS:
| 1 | 3 |
| 2 | 4 |
| 3 | 6 |
| 4 | 7 |

Probably your references are not right.  E.g. in Org-8.2 this file would
produce your observed result.
