Hello, It appears you are using the igraph package. You can get rid of the arrows using a few different methods.
You can make the graph undirected: new.graph <- as.undirected(old.graph) plot(new.graph) Or you can simply specify the size of the arrows as zero using either E(some.graph)$arrow.size <- 0 plot(some.graph) OR plot(some.graph, edge.arrow.size=0) There are many great plotting features with the igraph package available here: http://igraph.sourceforge.net/doc/R/plot.common.html Best, Gary On Apr 12, 2011, at 6:00 AM, r-help-requ...@r-project.org wrote: > Message: 77 > Date: Mon, 11 Apr 2011 15:09:26 -0700 (PDT) > From: kparamas <kpara...@asu.edu> > To: r-help@r-project.org > Subject: [R] plot - kamada.kawai layout without arrows > Message-ID: <1302559766984-3443258.p...@n4.nabble.com> > Content-Type: text/plain; charset=us-ascii > > Hi, > > I am plotting a graph with kamada.kawai layout. > > But I am getting direction arrows in the graphs. > Please let me know how to avoid this. > > g <- watts.strogatz.game(1, 2000, 5, 0.4) > > comps <- clusters(g)$membership > colbar <- rainbow(max(comps)+1) > V(g)$color <- colbar[comps+1] > > png(filename) > plot(g, layout=layout.kamada.kawai, vertex.size=2, vertex.label=NA) > dev.off() > > Please find attached the figure with arrows.. > http://r.789695.n4.nabble.com/file/n3443258/cdata1_plot.png -- Gary Weissman http://www.babelgraph.org/ g...@babelgraph.org [[alternative HTML version deleted]] ______________________________________________ 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.
