The issue is not `duplicate rows' but duplicated row names. You asked R
explicitly to make a column into row names -- if they are not suitable row
names, don't do that. You can remove duplicated rows later (see ?unique)
but you cannot have duplicated row names in a data frame so leave them as
numbers.
