Dear Achim,

Excellent. Thank you very much!

Dear helpers,
on the web I found a formula to get frequencies which I modified to my
needs, but it does not yet work well. An example:
|---------------------|
| [1, 2, 3, 4, 5] |
| [6, 7, 8] |
| [9, 10, 11, 12, 12] |
| 12, 12 |
|---------------------|
| 15 |
| 2 |
#+TBLFM: @5$1=vcount(@I..@II)::@6$1=vcount(map(<if(eq(#1,12),1,[])>,@I..@II))
With the first formula (@5$1) everything inside and outside the
brackets is counted, but with the second (@6$1), where I am asking for
the frequency of 12, only what is outside the brackets is considered.
How could I also include what is inside the brackets, so I get 4?
Thank you very much in advance!
Martin

The Calc manual tells you that vcount flattens nested vectors, vmap doesn't.
Try @6$1=vcount(map(<if(eq(#1,12),1,[])>,vflat(@I..@II)))
for the second formula.
