Hi I get a matrix with the columns named like "X13 X22 X1 X14 ...", i.e. not successively. That has it's good reasons, but now how can I rename the columns to "X1 X2 X3 ..."? Thanks a lot, David
If A is your matrix try:
cnames(A) = paste("X", 1:ncol(A), sep="")

Sorry, that should have been "colnames" rather than cnames; i.e.:
colnames(A) = paste("X", 1:ncol(A), sep="")

For a matrix m with k columns:
colnames(m) <- paste("X", 1:k, sep="")

This is what I would do:
cc <- NULL
for(i in 1:ncol(x)) cc <- c(cc, paste("X", i, sep=''))
colnames(x) <- cc
where x is your matrix.
Hope this helps,
Andy
