Hi all,

I have a matrix
a<-c(2,3,4,Inf)

> b<-as.matrix(a)
     [,1]
[1,]    2
[2,]    3
[3,]    4
[4,]  Inf

> range(b, finite=TRUE)[2] (this is the maximum)
[1] 4

There is a pre-def function to extract the location (in terms of rows) of
the value in the matrix.

In my example would be

3 (max is in the third row)

The maximum is in the position (row) 3.
