Hi, I need to draw a line segment between two points on different plots in the same multigraph.I've tried looking at the zoominplot function in plotrix but havent understood much.any help is appreciated ~Aks [[alternative HTML version deleted]]

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 R experts, I went through R mailing,Nabble R.I could not find solution.Can someone help me. I have undirected Graph. Here is an example of spreadsheet I have( Unique 3559 Nodes) snippet of 4 rows. Node1 Node2 Weights 1 2 5 2 3 30 2 4 30 1 4 5 3 4 30 1 3 2 I created a program reading the csv and created a Adjacency matrix.From the adjacency matrix I created graph.I am not sure the

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 <-

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

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

Could somebody program this kind of plot type to R, if none exists, based on mds or correlation tables or some more suitable method? What do you think about idea? Does it work? None similar or better exists? http://weightedassociationmap.blogspot.com/ Atte Tenkanen University of Turku, Finland

R-devel, I'm interested in looking at some examples of existing R packages that rely heavily on S4 classes to get a feel for varying styles and package organization techniques. Could you recommend any packages that might serve as a good starting point? Thanks in advance, Jeff

Dear R users I'm a novice user of R and have absolutely no prior knowledge of social network analysis, so apologies if my question is trivial. I've spent alot of time trying to solve this on my own but I really can't so hope someone here can help me out. Cheers! The dataset: I'm trying to predict the existance of links (True or False) in a test set using a training set. Both

Dear R-devel I have a function in a package that essentially provides a wrapper for a group of functions in another Suggested package (it sets appropriate defaults for the context, transforms output, etc). I've implemented this by verifying that the package was loaded with require(sna) and then do.call(snaFunName, args = args) The rDevel check is requesting that I use

Is anyone know some thing about sna package source code?? I have a question about sna source code, I need some functions in R sna package, so I check the source code. There is a function called efficiency in sna package, but I didn't find the any code about "efficiency", anyone know it? thank you [[alternative HTML version deleted]]

Hello, I work with two packages sna and graph from CRAN resp. Bioconductor. Both packages have a function called "degree". Therefore one of the functions is masked by the other and which one gets called depends on the order of loading. The problem is that both package do not have a namespace, therefore calling the masked function with "package::degree" does not work.

Hi all, An oddity that has existed for a long time in the IR is that PointerType derives from SequentialType. Per subject I propose to make PointerType derive from Type for a couple of reasons: - Values of type PointerType are unlike the other SequentialTypes (arrays and vectors) in that they do not hold values of the element type. By moving PointerType we can unify certain aspects of how the

Dear R users I created the graph at the bottom using xyplot in the lattice package. I added a title using the main="Title" command in xyplot, however it is plotted too close to the legend for my liking. To remedy this I increased the upper margin of the plot using plot(data, position = c(0,0,1,.9)) and attempted to move "SNA" upwards and to the right. I have tried using a

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 Guys, Do you any one know how to convert a long format table to an adjacency matrix used in sna? The long table looks like p1 p2 counts a b 100 a c 200 a d 100 b c 80 b d 90 b e 100 c d 100 c e 40 d e 60 and I want to convert it to an adjacency matrix which can be used in sna? Any methods will be appreciated! btw, besides sna package, is there any better package can be used in social

I've been using sna to work with some networks, and am trying to visualize them easily. My networks are hierarchical (food webs). All of the layout engines I've tried with gplot don't seem to plot hierarchical networks, as one would using dot from graphviz. While I could do all of this by outputting to dotfiles and running it through graphviz, the graphics I get from R are much

Hi folks, I am trying to install the sna package on a MacOS X 10.3.9 and 10.3.4. In neither case I have been able to get the R CMD Install command to succeed from the Terminal window. With 10.3.9 I get an error with the Make command, and with 10.3.4 I get an error on the Description(???) Has anyone out there been able to install it successfully on a Mac? Thanks Alex
