see ?degree for the degree and ?cor for the correlation. E.g.

mixing <- function(g) {
  el <- get.edgelist(g)
  deg <- degree(g)
  cor(deg[el[,1]+1], deg[el[,2]+1])
}

You need to modify the degree() call to take edge direction into account.

ps. FYI, there is also an igraph missing list, in case I miss your
messages on R-help and nobody else answers either.
Dear colleagues,

I'm trying to have a look at the Assortative and Disassortative (
http://en.wikipedia.org/wiki/Assortative_mixing) of the network I have.
But it seems that the igraph hasn't mentioned that yet.

I have to get the in/out degree of the vertices of each edge and calculate
the Pearson's Correlation coefficient which seems to be quite a huge task
for me. :(

So I wonder if anyone had done that before and give me some hints on it?

Thank you in anticipation!
