Re: [igraph] Betweenness Centrality

[Sanjin Pajo]

I'm sorry, I am using R and the function looks something like this: 
betweenness(graph, v=ids, directed=TRUE, nobigint=FALSE, normalized=TRUE). It 
completes with the warning message: integer overflow.

You did not mention whether you use the betweenness function from C, R or
Python, but all of these provide an argument for the betweenness function where
you can ask igraph to use "big integers". This is slower but does not suffer
from overflow issues.

All the best,
