Hi,

Yes, if you use -1 as a placeholder for missing attributes, igraph considers
that as a new type. How about simply taking the induced subgraph of all the
vertices for which you know the gender and then just calculating the
assortativity on that subgraph? Or, you could assign random genders to the
vertices where you don't know the gender, take 1000 realizations and then take
the average assortativity of these 1000 realizations.

For instance, if your graph has no edges, you will get a NaN. You will also get
a NaN if all the types are identical.
