Or you could use:
mat <- matrix(sample(1:25), 5, 5) mat which(mat==max(mat),arr.ind = T) Wayne -----Original Message----- From: Jim Gustafsson [mailto:[EMAIL PROTECTED] Sent: 25 August 2004 10:07 To: [EMAIL PROTECTED] Subject: [R] R-help Dear R users, I have just start working with R and would need some help. If you have a matrix as: [,1] [,2] [,3] [1,] 11 24 11 [2,] 16 29 16 [3,] 2 15 2 and you want the position where you can find the maximum value, in this case row 2 and column 2. How could you get the position? The values in the matrix is likelihood function values, and each row and column represent values from two parameters. So the idea is to seek which parameter values maximise the likelihood and therefore I need boot row and column position.
