Hello there, I am using the igraph package to build graphs from my data. If I plot a graph though, it's not easy for me to see what's going on. Does anybody know how to rearrange a graph to get a plot without too many crossing lines? Maybe other packages? Thanks a lot in advance for any pointers, -- D --------------------------------- [[alternative

Hi R-users, I'm using igraph for an undirected graph. i used clusters() igraph function to know the component size(subgraphs) as shown bellow: c <-clusters(g)    # component sizes size <- sort(c$csize, decreasing=TRUE) cat("Top 20 cluster of the graph","\n") for (i in 1:20) {   cat(i,"  size:",size[i] ,"\n") } Can anyone help how to extract the

Hi, I'm working on some social networks and I managed to create the graphs with labels and edges weight, but I would also like to change the size of the vertices according to the age of the persons in the network and the shape according to the gender. Now for the age, I have people with ages between 20 and 78, and I would like to have 4 categories (sizes): 20-35, 36-50, 50-65, >65. I have

Hello, I am exporting a graph in "gml" format from igraph 0.5.5. When I open the file in Cytoscape v.2.7 I can't map the color attribute that I assign to the graph when I export it from igraph.

Hi I am using igraph package in R. My goal is to read a network (in "pajek" format) and decompose the network into components. In addition, I am also interested in sending this output to to a file. I am having problem in while writing to a file! my code looks like this g <- read.graph ("F://test.net", "pajek") compo <- decompose.graph(g,

When the shape of all vertices is set to "square" and the size of the vertices is also set, one get following error (commands attached): Error in l[[which.min(sapply(l, function(p) (p[1] - x0)^2 + (p[2] - y0)^2))]] : attempt to select less than one element Is there a way to solve this problem?

Hi, I'm trying to do some basic social network analysis with igraph in R, but I'm new to R and haven't been able to find documentation on a couple basic things: I want to run igraph's community detection algorithms on a couple thousand small graphs but don't know how to automate igraph looking at multiple graphs described in a single csv file. My data look like something in

Hi I just tried out the new 0.1.0 release of beryl. Generally I do like the compiz fdo version, because I like the gconf integration and the metacity theme support in gwd. Also I think their configuration system is a complete mess, this beryl settings manager is completly bloated in my opinion. Anyway, I noticed they have quite a lot of plugins. While I found most of them nothing special, the
