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.
