Gabor, Here is a sample .csv file. Thanks,Jameson Date: Mon, 22 Apr 2013 22:14:24 -0400 From: [email protected] To: [email protected] Subject: Re: [igraph] I'm getting Different MST each time
Hi, unfortunately we cannot run your code because we don't have the .csv file. Please send some self-contained example that reproduces the problem, e.g. make up some toy data. See e.g.http://stackoverflow.com/questions/5963269/how-to-make-a-great-r-reproducible-example Thanks,Gabor On Mon, Apr 22, 2013 at 9:44 PM, jameson mcfarlane <[email protected]> wrote: Hello, I am creating a minimum spanning tree (MST) with i-graph. For some reason, I seem to get a different MST diagram (nodes in different order) each time I run it. For example, sometimes the primary tree node is say "Jon K.". Other times, it could be "Larry Z." Could any help with what I am doing wrong? Here is the code: library(igraph) tab <- read.csv("NewJam12.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=20, height=10) plot(mst, layout=lay, vertex.size= 5, vertex.size2=15, vertex.shape="circle", asp=FALSE, vertex.label.cex=0.5, vertex.color="green") _______________________________________________ igraph-help mailing list [email protected] https://lists.nongnu.org/mailman/listinfo/igraph-help -- Gabor Csardi <[email protected]> MTA KFKI RMKI _______________________________________________ igraph-help mailing list [email protected] https://lists.nongnu.org/mailman/listinfo/igraph-help
