Thank you for implementing assortativity in igraph-0.6, it's nice addition.
However there is something there what I don't understand.
Assortativity.degree gives different results than assortativity itself.
If I understand manual properly it should give the same values.
> assortativity(g1,degree(g1)-1,directed=TRUE)
[1] 0.1368699
> assortativity.degree(g1,directed=TRUE)
[1] 0.1546312
It works fine when directed=FALSE. I'm using
igraph_nightly_0.6-1899-20100505 under R-2.8.1 .
