[igraph] transitivity barrat

[Umberto77]

Hi,

I'm working with a directed multiple and with loops weighted graph, I cannot measure transitivity (type=c("barrat")) since I get:

numeric(0)

I used as.undirected with the collapse mode first. Still, I get

numeric(0)

Sorry for the silly questions, but I prephare talking silly to get know things better.

Secondly, I read someone else was looking for a weighted directed version of Barrat's (Newman, 2005), but I could not get how to do it, and I also need to account for multiple edge and/or loops.

Thanks,

Umberto M.
