Hi Everyone,
I currently have a minimum spanning tree (MST) looking like this: see attachment msta.gif. But I want it to look like this: mstb.gif Here is the code (below) using igraph. I'd greatly appreciate any help. Thank you library(igraph) tab <- read.csv("NewJam6.csv") tab <- tab[,-1] g <- graph.adjacency(as.matrix(tab), weighted=TRUE) V(g)$label <- V(g)$name mst <- as.undirected(minimum.spanning.tree(g)) lay <- layout.reingold.tilford(mst, root=which.max(degree(mst))-1) lay <- cbind(lay[,2], lay[,1]) # rotate x11(width=15, height=8) plot(mst, layout=lay, vertex.size=5, vertex.size2=10, vertex.shape="circle", asp=FALSE, vertex.label.cex=0.7, vertex.color="green") From: address@hidden To: address@hidden Date: Wed, 8 Aug 2012 16:58:51 +0000 Subject: [igraph] Square Matrix /MST
Hello Everyone,
I'm rather new to igraph. I am using Windows 7 to create an MST (Minimum Spanning Tree) with the attached data file. However, I keep getting that this data is not a square matrix. Any kind of help will be much appreciated. Thank you, Jameson _______________________________________________ igraph-help mailing list address@hidden https://lists.nongnu.org/mailman/listinfo/igraph-help |
