I have --8<---------------cut here---------------start------------->8--- A graphNEL graph with undirected edges Number of Nodes = 41 Number of Edges = 816 --8<---------------cut here---------------end--------------->8--- each edge has a weight. how do I tell plot() to respect edge weights? (higher weight => thicker, straighter and shorter edge). I suppose I should be using the edgeAttrs argument, but I cannot figure out how. Thanks. PS. I also have vertex attributes which indicate vertex size. PPS. I got the graph object from the igraph object using igraph.to.graphNEL(http://igraph.sourceforge.net/doc/R/graphNEL.html); it would be nice to be able to create a graph from a list of vetexes and their sizes and a list of edges and their weights, like (http://igraph.sourceforge.net/doc/R/graph.data.frame.html). -- Sam Steingold (http://sds.podval.org/) on Ubuntu 12.04 (precise) X 11.0.11103000 http://www.childpsy.net/ http://truepeace.org http://honestreporting.com http://camera.org http://think-israel.org http://dhimmi.com Those who can laugh at themselves will never cease to be amused.
