Sounds like you have imported the data, perhaps using 'header = TRUE' either without an actual header row of column names or perhaps an incomplete or improper (not syntactically valid) header row. If you are getting X's (and not V's) pre-pended to the column names, that sounds like the result of make.names() on your data. See ?make.names If you don't have a header row in the imported data set, you can use the 'colnames' argument in read.table() to explicitly provide them. Just be sure to set 'header = FALSE'. If there is a header row, but it is problematic, set 'header = FALSE' AND 'skip = 1', which will skip over the first row in the incoming file.
