Re: COMBIN

["Prof. John C Nash" <nashjc uottawa ca>]

Slightly off-gnumeric, R (www.r-project.org) with which Gnumeric has had friendly 
exchanges, can do the job:

> combn(5,2)
     [,1] [,2] [,3] [,4] [,5] [,6] [,7] [,8] [,9] [,10]
[1,]    1    1    1    1    2    2    2    3    3     4
[2,]    2    3    4    5    3    4    5    4    5     5
>

In the past there were some ways to call R from Gnumeric, but I fear they are not 
currently functional, buy welcome correction on that.
