Subject: formatting org-babel output
Date: Wed, 22 May 2013 07:18:40 -0400 [thread overview]
Message-ID: <CAEtzV1ZFbMjg3fgYcUMYVUQ2tV5dSiNcE-5yF7w_GYvs3saPfQ@mail.gmail.com> (raw)
I am using org-mode and babel with R for reproducible research. I
would like certain numbers in the output tables to be formatted for
easier reading - such as eliminating decimals and adding commas for
readability.
The best I came up with is to use a TBLFM line at the bottom of my
results table using a function I found on the ElispCookbook on
emacswiki. A simple example is below that doesn't require R to
reproduce.
It's a two step process currently to execute the R code in org-babel
and then jump to the result table TBLFM line and Ctrl+c Ctrl+c to
format the table
Is there a better way to format table outputs for simple things like
currency? I would be content if it's only during the org export
process too
#+BEGIN_SRC emacs-lisp
(defun group-number (num &optional size char)
"Format NUM as string grouped to SIZE with CHAR."
; Based on code for `math-group-float' in calc-ext.el
(let* ((size (or size 3))
(char (or char ","))
(str (if (stringp num)
(number-to-string (string-to-number
(replace-regexp-in-string "," "" num)))
(number-to-string num)))
(pt (or (string-match "[^0-9a-zA-Z]" str) (length str))))
(while (> pt size)
(setq str (concat (substring str 0 (- pt size))
char
(substring str (- pt size)))
pt (- pt size)))
str))
#+END_SRC
#+RESULTS:
: group-number
#+NAME: example-table
| 100000000.55 | a |
| 23000 | b |
| 3000 | c |
| 40004 | e |
| 5000 | 3 |
This is the table I want formatted
#+BEGIN_SRC emacs-lisp :var data=example-table
data
#+END_SRC
#+RESULTS:
| 100,000,000.55 | a |
| 23,000 | b |
| 3,000 | c |
| 40,004 | e |
| 5,000 | 3 |
#+TBLFM: $1='(group-number $1)'
