Hi, I have this matrix
unsorted$A with 5 columns (all numeric). Currently I'm sorting the columns like this: sorted$A[,1] <- sort(unsorted$A[,1]) sorted$A[,2] <- sort(unsorted$A[,2]) ... I have tried doing sorted$A <- unsorted$A[do.call(order, data.frame(unsorted$A)),] but it sorts the first column then the 2nd column which it ties to the 1st column, then the 3rd which is tied to the 2nd, etc. I need all the columns to be independently sorted. Any help is appreciated. Desmond _______________________________________________ R-SIG-Mac mailing list R-SIG-Mac@stat.math.ethz.ch https://stat.ethz.ch/mailman/listinfo/r-sig-mac
