R help - Jun 2010 - merging data frames

Hi,

is it possible to merge two data frames while preserving the row names of
the bigger data frame?

I have two data frames which  i would like to combine. While doing so I
always loose the row names. When I try to append this, I get the error
message, that I have non-unique names. This although I used unique command
on the data frame where the double inputs supposedly are

thanks for the help

Put the rownames as another column in your dataframe so that it
remains with the data.  After merging, you can then use it as the
"rownames"
