Thank you Gabor.
I get the weighted closeness centrality but the betweenness one is still unweighted.

Why do you think this? This is what I get:

> g <- graph.ring(10)

> E(g)$weight <- runif(ecount(g))

> betweenness(g)   # weighted

 [1] 10 12 13 13 11  8  5  3  4  7

> betweenness(g, weights=NA)    # unweighted

 [1] 8 8 8 8 8 8 8 8 8 8

So can you send me some code that reproduces your problem?

Thanks,

Gabor

 

how can I order the calculation of the weighted or unweighted centrality.

Than you again
Rachid
