[igraph] Alpha centrality with valued graphs

[Brandon J Kinne]

Dear all:

Bonacich's 2001 paper mentions that alpha centrality can be calculated 
not only on directed, but also valued graphs. However, I can't seem to 
get igraph to consider edge weights when using alpha.centrality. Am I 
missing something here, or does igraph simply not allow valued graphs 
with alpha.centrality? I know there is other software, such as UciNet, 
that does calculate alpha centrality for valued graphs, but I'd much 
prefer to stay within the R environment. Thanks in advance for the help!

Best regards,

Brandon Kinne
