MAT <- matrix(runif(10000 * 6), 10000, 6) # TXT format write.table(MAT, "C:/yourmatrix.txt",col.names=FALSE,row.names=FALSE,quote=FALSE) # XLS format write.table(MAT, "C:/yourmatrix.xls",col.names=FALSE,row.names=FALSE,quote=FALSE,sep="\t") HTH, Jorge On Thu, Jul 31, 2008 at 1:53 PM, Max <[EMAIL PROTECTED]> wrote: > Marc, > > this is very handy.
