Yes but why? If you want to have some names A.whatever which can repeat
itself then does not use it as row names and put it in separate column
called e.g. mynames. In this column you can have any number of
replications - if I am not mistaken somebody suggested it already.
You can imagine row.names more like row numbers and in that case you
probably do not want to have several row numbers let say 42, do you?
