Hello, I am calculating 'Betweenness' of a large network using R. Currently, I have the node-node information (City1-City2) in an excel file, present in two columns where column A has City1 and column B has City2 that city1 is connected to. These are the steps that I go through to calculate betweenness of my network. a) Convert the City1-City2 (text) into Number1-Number2 in the excel

I am getting some unexpected results from some functions of igraph and it is possible that I am misinterpreting the vertex numbers. Eg., the max betweenness measure seems to be from a vertex that is not connected to a single other vertex. Below if my code snippet: require(igraph) my.graph <- graph.adjacency(adjmatrix = my.adj.matrix, mode=c("undirected")) most.between.vert <-

Hi, I have the following problem. I have 5 phones behind the same nat (canreinvite=yes). it works fine to receive calls and to make calls. sound quality is good, so everything works fine. The poblem is that the phone behind nat cant call each other. It works if canreinvite=no. But i want to do this. Does anyone have an idea? Regards, cjk.

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

I would like to apply network measures (such as betweenness centrality, upper boundedness, etc.) to a weighted graph with non-integer weights, defined by a euclidean distance matrix. The package sna provides the measures that I want to use, but seems only to operate on binary graphs. I have read work by Mark Newman (http://aps.arxiv.org/abs/cond-mat/0407503/), who suggests that a weighted graph

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 everyone, I have successfully created and analyzed my network data. I am new to R, and Network Analysis too, but I want to color my vertex based on some of the centrality measures calculated. Can someone point me in the right direction? Again, I am new to R, but given how powerful R appears to be, I figure this is probably pretty easy to do, I just wish I could figure it out. Many thanks

Hi R Users I am working with the very useful SNA package (v.2.2) in R and have a query I hope you may be able to help out with: I have been using gplot commands to plot an SNA graph. Here's the code and output: library(sna); library(network); library(RODBC) setwd("c:\\temp") x = read.csv(file = "testforr.csv") Total.Sold=c(1,3,6,1,3,6,1,3,6,6,9) src=c(1:10,1)

Hi everyone, I'm writting a script that will open multiple files in a single folder and then will do some calculations to finally save everything in a big table. So here is the pseudo code #read all files in the given directory myfiles <-list.files("c:\\myDir") #initialize table ??? #loop through files for(f in myfiles[-1]) { netMat <-

Hi, I had asterisk installed, ISDN-adapter, some x-lite software-phones and I can call betweens the softphone- and 'normal' phones during the ISDN-card. 2 questions now 1) Is it posible to create policies, so that some SIP-users can dial ALL numbers, and some SIP-users not are allowed to dial eg. 900xxx-numbers, 30xxxxxx (mobilphones), 40xxxx(long distance) and if possible on time...

Dear R-users, These days, I have been struggling to install the package sna on my Ubuntu 8.04 laptop. My R version is currently R 2.7.2. And I had no trouble installing any other packages (including network). However when I run 'install.packages("sna")', compilation of C codes is ok, but a syntax error is reported when building help pages and sna does not want to install. I

Hello All, I went through lot of searching for papers to do clustering on Co-Authroship.I ran SNA metrics on my Undirected Graph(betweenness,Closeness,Eigen Vector) using R. After running the sna Metrics I found important nodes and did clustering on those nodes based on Binding strength .This clustering is done through if they are connected.I would like to do clustering based on Weight of the
