[R] how to rename rows/columns of a matrix?

[apjaworski@mmm.com]

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

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
