Hi,

Given test <- matrix(c(0,2,0,1,3,5), 3,2)

> test[test>0]
[1] 2 1 3 5

These are values >0

> which(test>0)
[1] 2 4 5 6

These are array indices of those values >0

> which(apply(test>0, 1, all))
[1] 2

This gives the row whose elements are all >0

I can't seem to get indices of rows containing one or more elements >0
