r - Unexpected symbol in read.table -


i trying read data with:

data <- read.table('pwaves.txt', header=true, row.names=1, sep='\t')

works ok,except got x in front of each number.like this:

      x5   x6   x7 fcm 13.0 12.5 11.8 gk  10.9 10.5 10.2 gg  12.0 11.0 10.8

why?

isn't because headers numeric, r checks , transforms it. try add check.names=false

     data <- read.table('pwaves.txt', header=true, row.names=1, check.names=false, sep='\t')
