Re: [R] Replacing values in a data.frame/matrix

how about: m <- matrix(c(1,2,3,2,1,3,3,1,2), ncol = 3, byrow = TRUE) perm <- c(1, 3, 2) out <- perm[m] dim(out) <- dim(m) out I hope it helps. Best, Dimitris On 3/8/2011 4:05 PM, Thaler, Thorn, LAUSANNE, Applied Mathematics wrote: Hi all, Suppose we have the following matrix m<- matrix(c
