Subject:  [igraph] problem with alpha.centrality 
Date:  Mon, 22 Oct 2012 17:28:25 +0200 
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")
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
