I want to plot a power law fit for my data (in .net format --- pajek format)
syntax for that in R is

d <- degree (g, mode="in")
power.law.fit (d+1, 2)

igraph package, version 0.5
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

igraph node placement
Hello R users,
I've just defended my PhD dissertation, and I'm engaging in discussions with
the "ruler lady". She has some problems with my figures. The problem is
that my nodes overlap the text that I've put inside of them.
Here is a url for the figure:

igraph and plotting connected components
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,

layout of igraph
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

save the layout using igraph
Hi R users,
I am using built-in functions in igraph package to draw networks . I need
to compare several network with exactly the same structure but with edge
hightlighted differently. I am wondering if there is a way to save the
layout so that every graph will look the same as each other except for the
colors of edges. Or is there any parameter I can set for this purpose??
Thanks in advance,

[R-SIG-Mac] Plotting Chinese characters
Alberto,
you simply need a font that has those characters. For example on 10.6 this works:
plot.new(); plot.window(0:1,0:1); text(0.5,0.5,"??",cex=10,family="Hei")
You may want to check your system for fonts that you can use (those that have chinese characters when you click on them in Font Book). There are a lot of fonts that work like STSong, STFangsong, LiSong Pro,

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

from within R gives the following errors:

function: ploting an igraph object within lattice
Hi, I would like to be able to develop a function to plot an igraph object
with lattice (trellis type displays will be usefull for grouping etc).
Anyway, I mostly feeble
Igraph requires that you convert two columns of data two an igraph object
and to be able to plot the graph...I have tried a very, very simplistic (if
not naive) approach and surprise, surprise, it didn't work.

Trouble compiling igraph. . .
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.
