Dear all, I'm doing some experiments with igraph and in particular with graph layouts. I can't figure out how to apply a layout to a given (real) graph avoiding node overlaps.
In the following example if the variable NumOfNodes is setted to a small value (10) the layout function generates a plot without node overlaps. But even with a not-so-big number of nodes (50) plotted graph has almost all nodes overlapped by neighbors vertices. The problem gets even worst if I increase vertex size. # R code require(igraph) NumOfNodes <- 10 g <- barabasi.game(NumOfNodes) g$layout <- layout.reingold.tilford(g) plot(g) NumOfNodes <- 50 g <- barabasi.game(NumOfNodes) g$layout <- layout.reingold.tilford(g) plot(g) Actually I'm using GraphViz which has an option to avoid overlaps but I can't find something similar in igraph documentation. Can someone point me to the rigth direction ? Thank you in advance. a -- View this message in context: http://r.789695.n4.nabble.com/igraph-graph-layout-and-node-overlaps-tp2535297p2535297.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
