For a start, you are missing a quote and a parenthese on the
statement; probably should be: (another quote was also missing)
n<-subset(m, select=c("X1", "X7", "X12","X15", "X22", "X26", "X31",
"X34", "X39", "X44", "X51", "X58"))
Not sure what you want with the rownames; an example would help and
post with 'dput'.
