Dear all, There is a weird behaviour of alpha.centrality() and there seems to be a problem with the implementation, which I do not seem to be able to access.
I have a graph g with an edge attribute which I named "weight" (E(g)$weight). When I call the different forms I get some weird things alpha.centrality(g, weights = NULL) alpha.centrality(g) I get the same result (according to the help file I should not). When I try alpha.centrality(g, weights = "weight") I get the same plus the error (even though it should not): Warning message: In alpha.centrality.sparse(graph, nodes, alpha, loops, exo, weights, : NAs introduced by coercion This is independent on how I name the edge attribute I want to use to weigh edges. Is there a problem in the implementation of weights in alpha.centrality? Many thanks for any help on this. Kind regards, Bob
