I am very sorry to bother you all again on this, as I tried but still couldn't
figure out the exactly how to do this on my own.
I added the code to the VertexDendrogram Object. What would be the code
examples that I'd use this function?
Right now I have:
import igraphg =
igraph.read('/home/xiao/Desktop/tag.NET',format="pajek")dendrogram =
g.community_edge_betweenness()
What's next to prevent as_clustering freaks out?
