Hi Fredrik,
What you need to do is to massage your table a little to get it into the
appropriate structure and then use the rgroup and n.rgroup options.
Here's an example using the Titanic data that come with R. Note that
this is not necessarily (or even remotely likely?) the best way to get
your data into the shape required, but hopefully it shows you what, in
general, you need to do. You might find that you don't need to use
ftable at all, you might find other ways of creating the table you need.
In the example below, note in particular what x and x2 look like.
> library(Hmisc)
> x <- ftable(Titanic, row.vars = 1:2)
