I think that, as order() always

Actually, this may be a solution I was looking for! Note that it assumes that

Hello,
I'd like to rank rows of a data frame similar to what rank() does for
vectors. However, ties should be broken by columns that I specify. If it
is not possible to break a ties (because the row data is essentially the
same), I'd like to have the same flexibility that rank() offers. Is

Hi!
in R? Basically, what I need is a mixture of order() and rank().
While the former allows to specify multiple vectors, it doesn't
provide the flexibility of rank() such that I can specify what
happens if ties can not be broken.
An example of this simple problem would clarify this greatly.
