If you used read table    or one of it s ilk  e g  read csv    then the easy fix is to change the call to  read table file    quot foo txt quot   row names   1         where      are the other arguments you needed used  The row names argument takes the column number of the data file from which to take the row names  It need not be the first column  See  read table for details info  If you already have the data in R and can t be bothered to re-read it  or it came from another route  just set the rownames attribute and remove the first variable from the object  assuming obj is your object  rownames obj   lt - obj   1      set rownames obj  lt - obj   -1               remove the first variable
