I have a graph with some vertex attributes: IGRAPH UNW- 9105 1110486 -- + attr: name (v/c), count (v/n), weight (e/n)
and I have a community structure on it. how do I compute, say, the vector of sums of counts (vertex attribute) of communities? so far I only came up with sapply(1:length(community.ml), function (i) sum(vertices[vertices$vertex %in% attr(which(membership(community.ml) == i),"names"),]$count)) where `vertices' is a data frame which was used to create the graph in graph.data.frame(edges.all, vertices = vertices) I suspect that there is a better way. what is it? -- Sam Steingold (http://sds.podval.org/) on Ubuntu 12.04 (precise) X 11.0.11103000 http://www.childpsy.net/ http://dhimmi.com http://mideasttruth.com http://thereligionofpeace.com http://openvotingconsortium.org If you misspell "milk" 4 times, you can get "beer". _______________________________________________ igraph-help mailing list [email protected] https://lists.nongnu.org/mailman/listinfo/igraph-help
