I would like to apply network measures (such as betweenness centrality, upper boundedness, etc.) to a weighted graph with non-integer weights, defined by a euclidean distance matrix. The package sna provides the measures that I want to use, but seems only to operate on binary graphs. I have read work by Mark Newman (http://aps.arxiv.org/abs/cond-mat/0407503/), who suggests that a weighted graph can be transformed into an unweighted multigraph, to which such measures can be applied. It seems that the package giRaph contains a function to handle multigraphs, but there is no example in the manual to show how it is used. I am also not sure whether this multigraph structure can be used as input into the relevant functions in the sna package. Can anyone advise?
Many thanks, Andrew Wilson ______________________________________________ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
