Re: [O] [babel] inline call within table formula?

[Eric Schulte]

Hi Eric,

The `sbe' macro can be used to evaluate code blocks in table formula.

For Example:

|   1 |
|   2 |
|   3 |
|   4 |
|   5 |
|   6 |
| 3.5 |
#+TBLFM: @7$1='(sbe mean (lst @address@hidden))

#+source: mean
#+begin_src emacs-lisp :var lst=()
  (let ((num (car lst)) (nums (cdr lst)))
    (/ (float (+ num (apply #'+ nums))) (1+ (length nums))))
#+end_src

See the documentation string of this macro for more information.

Best -- Eric
