Hi Tassilo,
I can see that this could be confusing, and maybe it should throw an
error.
The use-ase fo this are running means as column formulas
that would be undefined for he first few rows in. Consider
the following table:
| i | nn | mean of last 3 |
|---+----+----------------|
| 1 | 4 | 4.00 |
| 2 | 7 | 5.50 |
| 3 | 2 | 4.33 |
| 4 | 4 | 4.33 |
| 5 | 5 | 3.67 |
| 6 | 7 | 5.33 |
| 7 | 9 | 7.00 |
| 8 | 22 | 12.67 |
#+TBLFM: $3=vmean([@-2$-1..$-1]);%.2f
I am not sure how common this use is and who would
be hurt by turning this behavior into an error.
