similar to: function: ploting an igraph object within lattice

I am having trouble plotting one of my graphs (think graph theory graph with edges and vertices, not scatterplots or histograms). For some pairs of vertices, I want multiple edges to be visible in my graph. As an example of this, in my script below, I want two edges to be visible from vertex 1 and vertex 9 (among some others) yet when I plot it, only one edge is visible.

igraph is a package for graphs and networks. It has a C core and uses a simple and fast graph representation allowing millions of vertices and edges. NEW FEATURES: - We use the ARPACK library for graph related eigenvalue problems, like Page Rank calculation, Kleinberg's hub and authority scores, eigenvector centrality, etc. There is also a generic interface if someone wants to use

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

Dear r-help, I create a graph of my baysian network. I use the package igraph. The names of vertex are within the circle, I would leave them outside the circle? > E(g)$color <- "black" > tkplot(g, ,vertex.label=names,layout=layout.kamada.kawai, edge.color=E(g)$color) Best Regards [[alternative HTML version deleted]]

Hello, I am using the plot.igraph function in the igraph package to plot a network. How do I keep vertices from overlapping? One option would be to pass an argument that restricts vertices to occupy the same coordinates given their size. A second option would be to increase the area of the plot (and multiply the distance between vertices with a constant) while keeping the size of vertices the

Dear R users, I am trying to draw a network using igraph package. I intend to place the hub nodes (the ones with the relatively more connection with other nodes) in the center of the graph. Also, the graph need to be in the fashion that the higher the correlation between two nodes is , the closer the two nodes will be. Is there any layout that can help or any other way to do this? Thanks in

I have a number of (directed) graphs based on social groups, where the members have expresed likes and dislikes in respect to the other members. tkgraph makes it simple to draw the graphs in a very pleasing way, but I would like to differentiate between positive and negative relations in the graph by having the edges for the negative relations dashed and the positive ones continuous. Is

Hi R users, I got warning messages when installing the package, and I pasted the messages below. I checked updates that my R-studio is already the newest version. I don't know how to solve the problem. Thanks for your help. > library(igraph) Error in dyn.load(file, DLLpath = DLLpath, ...) : unable to load shared object

Hello, I'm having trouble getting the igraph package to load on Solaris. I can get igraph to compile and install from a local directory without issues using simply "R CMD INSTALL igraph", however "library(igraph)" from within R gives the following errors: Error in dyn.load(x, as.logical(local), as.logical(now)) : unable to load shared library

Been and R-user for about 5 years now in an industrial setting, and always find the mailing list most helpful. I have run into problem compiling igraph on R. I have contacted the maintainer of igraph, and he has determined that it is not an igraph problem. System is FreeBSD 7.2, R-2.10.1 [also have a sandbox machine running FreeBSD 7.3, R-2.11]. Both machines fail the installation of igraph.

Dear All, we have released version 0.6 of the igraph package today. This is a major new version, with a lot of new features, and (sadly) it is not completely compatible with code that was written for the previous igraph versions. (See "Major new features" below for details.) I have included below a list of (bigger) changes. Please see the details in the release notes and the NEWS

Hi! I want to use R for network analysis and have tried to install the 'igraph' package. Unfortunately, the installation is aborted by an error: --snip-- gcc -std=gnu99 -I/usr/lib64/R/include -DNDEBUG -I/usr/local/include -DUSING_R -I. -Ics -Iglpk -Iglpk/amd -Iglpk/colamd -I/usr/local/include -fmessage-length=0 -O2 -Wall -D_FORTIFY_SOURCE=2 -fstack-protector -funwind-tables

I have R 2.15.0 running under Windows 7. I installed the igraph 0.5.4 package from a zip file. When I attempt to load igraph using "library(igraph)", I get the error package igraph is not installed for arch=x64.  When I repeat this using the 32-bit version of R, I get the same basic error but with "arch=i386" instead of x64.

Dear R users, I'm using graph library to create a mesh-like network topology and implement a load balance routing algorithm. The current implementation uses graph, RBGL, and Rgraphviz libraries. I have a few attributes on every edge to represent the network loading and capacity, and I frequently update these values. However, I found it works so slow and right now I'm consider rewriting it
