RE: [R] duplicate row importing issue

Dear David,

If there is one fewer variable name in the first row of the data file than fields in the remaining rows, then read.table() will treat the first entry in each row as the row name. Simply add a new first variable (such as "name") to the first row, and specify header=TRUE in the call to read.table(). (Of course, this assumes that I've correctly guessed the source of the problem.)

I hope that this helps,
 John
