Hi, I was wondering how can I consider weights in the edges in order
to calculate closeness centrality?
Weighted centrality calculations were not included in igraph 0.5.1 but
they are already implemented in the development tree, see:

If you feel brave and you are willing to recompile igraph from source,
I can send you the current development branch. (In this case, please
let us know whether you are using igraph from C, R or Python).
