Hi Gabor,

If I want to use the weighted edge betweenness community detection algorithm in R, is it enough to just use
edge.betweenness.community(G)?
Namely, it is no need to add arguments about edge weights in the graph.
Thanks.
Regards,
chen

I think so, because when you calculate shortest paths, you want edge
weights to represent distances.
