[igraph] weighted centralities

[hamaina rachid]

Dear all,

I have a spatial network that i transformed to a weighted graph by distances, and i want to calculate weighted closeness and betweenness centralities.
Does igraph do that? i took a look but i understood that igraph centralities calculation ignore weights.
is there another package that do that? i looked sna, RBGL, network, tnet, spatstat and none could do what i want.
any kind of help is welcome.   

Thank you very much
sincerely
