Does R have graphlets?
I've been experimenting some with the graphlets which S-Plus 6.1 has. Is
there
something similar in R? I've looked through documentations, and at SJava,
but haven't found it.
(If you don't know what a graphlet is, here's what it appears to be:
a graphlet is a binary file that encodes information about
a graph. Java uses spgraph.jar to display the graph and allow certain

graphlets -- more
I have already recieved two very helpful replies. Let me describe the
problem we are trying to solve more clearly -- one of the suggestions was
along a line I'd never thought of, and I'd like to encourage more!
R is being used in a microarray/QC situation, in essentially a batch
mode. The applications that are "running the show" in terms of interacting

graphlets
Naras presented something with similar functionalities using SVG a couple of
years ago, and since then the svgdevice package had been made available. I
do not know SVG myself, but according to Naras, it's all possible.
Best,

ergm crashes
Dear all, I am doing a social network analysis using ergm. I import a rectangular matrix of data and then I build a network using the following command: ng <-network(mat,directed=FALSE)
I then attach vertex names using commands like this: set.vertex.attribute(ng,"SchoolType",mSchType) where SchoolType can take six different/unique values.
Then, I run ergm models successfully using

multiple values for a factor using nodematch in ergm()
Greetings, and many thanks for any insight you can offer.
I have a network object on which I'd like to simulate an ergm() using
{statnet}. Since the network object is large, I have not copied it here.
Each vertex has an attribute "language" which can take on integer values
greater than or equal to 1.
Is there a way to use the nodematch argument of ergm(), such that it

Efficient deterministic algorithm for Matching Weighted Graphs with bounded degree.
Hi Petr,
The following is different line of thought which is posted in different form, maybe you have some wise input on it.
"I need to find Efficient(tracktable) deterministic algorithm for Matching Weighted Graphs with bounded degree. Now we all know Graph matching is non-tractable but when degree of vertex has upper bound are there any tractable algorithm? Does this special case comes

Plotting Mean in plotting degree distribution
Hi,
I am plotting degree distribution of a graph using the function,
library(igraph)
dd1 = degree.distribution(G)
plot(dd1, xlab = "degree", ylab="frequency")
I would like to plot the mean of the distribution as a vertical line in the
attached plot.
Please let me know how to do this.
Thanks,

ergm model, nodematch with diff=T
Dear all,
I am new to network analysis, but since I have good data I started to read
about it and learned how to use the ergm and related packages. I generally
get interesting results, but when I run a model including sociality and
selective mixing effects for different groups, the model runs (and
converges) but I get a warning as follows:
mod <- ergm(network ~ edges + gwesp(0, fixed=T) +

Exporting a method to a cluster object
Hi,
This is my first message to this list. It would be great if people here
could help me with the following problem (self-contained code example
below):
I have a list of matrices and would like to apply a summary function to
the matrices in the list. The matrices represent social networks,
therefore I need to apply some specialized summary functions provided by
the ergm package. These

Compilation error during package installation

I am a Newbie for R. I just installed R-base on my notebook with
openSuSE 11. However, I always got compilation errors in installing
add-on packages. For example, when installing "igraph" I got the
following error:

igraph 0.6 released
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

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.
