[R] row.names in read.table()

[Ko-Kang Kevin Wang]

Hi,

I was trying to read in the following data set by using:
  gas <- read.table("gas.tab", header = T)
when I got the error message:
  Error in "row.names<-.data.frame"(*tmp*, value = row.names) : 
          duplicate row.names are not allowed

Any help are appreciated.

Thanks,

Ko-Kang Wang
