Hi, these are the proper channels for igraph help: http://igraph.org/r/#help
As for your questions, please consider reading the docs: http://igraph.org/r/doc/plot.common.html If you have specific questions, please post to the igraph-help mailing list or at stack overflow. Please make sure that you include a reproducible example: http://stackoverflow.com/questions/5963269/how-to-make-a-great-r-reproducible-example Gabor On Tue, Feb 10, 2015 at 5:21 AM, 赵鸿丰 <[email protected]> wrote: > Dear Sir/Madam: > > Thanks for your tips, a rookie like me > could use igraph to draw a social network graph from a document. > > And the code is very simple: > > #load the data of directed waighted social network > snet<-read.csv("E://exp//RoA.csv", header = TRUE, ) > > #drawing the graph of social network > library(igraph) > > #prepare data in the form of data frame > relations<-data.frame(from=snet[,1],to=snet[,2], directed=TRUE) > #build the graph data frame > conv<- graph.data.frame(relations, directed=TRUE) > #output > plot(conv, layout=layout.fruchterman.reingold, , vertex.size=5, > edge.arrow.size=0.2, > vertex.label.dist=0.2,) > > Now I am facing another problem: the clarity of the SN graph. > > > My SN graph seems like a mess because vertexes, arrows, and labels are all > crowed in the middle of the plotting area, just like follows: > > > > I tried to modify the elements of SN graph, include following details: > > 1.
