Hello, I'm a student who want to use the R social network analysis package. I have a question: can this package analyse dynamical networks (network changing over time)? I didn't find this functionality in the package's user manual. Thank you Davide [[alternative HTML version deleted]]

Hello, I am an italian student, who is trying to use R 2.3.1 with Ubuntu 6.10 (last version). When I try to use the plot command, I get the error: "could not find any X11 fonts Check that the Font Path is correct" How can I solve this problem? Thank you very much Davide [[alternative HTML version deleted]]

Hi, I an new to R and I realize this may be a silly question, but I searched the manuals and the list archives and can't find the answer. When I read data from R I get a dataframe with labels for rows and columns. SNA however asks for pure adjacency matrices, and if I try to use the dataframe gives an error message. What should do? Thanks a lot Jorge A. Colazo U. of Western Ontario

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

1 down vote favorite my problem is the following: I am using the R SNA package for social network analysis. Lets say, my starting point is an edgelist with the following characteristics. Every row contains a firm name, the ID of a project they are involved and further characteristics, let's say the projects year. Firms can be in several projects, and one project can consist of a

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]]

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

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

I am trying to use the lnam autocorrelation model from the SNA package. I have it running for smaller adjacency matrices (<1,500) it works just fine but when my matrices are bigger 4000+. I get the error: > lnam1_01.adj<- lnam(data01$adopt,x01,ec2001.csr) Error in optim(rho, n2ll.rho, method = method, control = control, beta = parm$beta, : initial value in 'vmmin' is not

Estimados Le consulto porque estoy intentando presentar unos datos de alguna forma un poco distinta, salir un poco de la costumbre. Primero describo los datos: Suponiendo una secuencia: golpe al auto -> torura de vidrio -> rotura de aciento otro auto golpe al auto -> -> rotura de aciento , a este por alguna causa no se le rompio el vidio o esa información es desconocida.

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

Hello, I have several "linked list" format network files that I'd like to read into R. Although I found a function to export files in .dl format, I could not find a function to read files in such format. Is there any quick way to read linked-list format files into R? Thank you very much. Jorge Colazo PhD Student University of Western Ontario [[alternative HTML version deleted]]

Hi there, I am doing some network analysis working with k-cliques and over time I want to see what nodes are members of what cliques and how big these cliques are. I have managed to produce a matrix which shows which k-cliques each node is part of over the 100 time periods (slow though) but I cannot seem to calculate the size of each k-clique which is actually just a count. Basically I have a

Hey all, I'm looking for a plotting method for two-mode networks. Having a n x m matrix where n is the first set of entities/ actors and m representing the second set, I want to colour both sets of actors differently. I tried "plot.network" from the network-package, but I did not succeed. Even the proposed solution from Gabor Grothendiek

Hi, I have a 500x 53380 sparse matrix and I am trying to dichotomize it. Under sna package I have found event2dichot yet it doesnt recognize sparse matrix and requires adjacency matrix or array. I tried to run a simple loop code for (i in 1:500) for (j in 1:53380) if (matrix[i,j]>0) matrix[i,j]=1 yet this takes a lot of time to run, I mean it has been last two hours and it is stil running.

Hi, Does anyone know of a package in R that has a function to convert network data (e.g. an adjacency matrix or ) from 2-mode to 1-mode? I am conducting social network analysis. I know that Pajek has this function under Net --> Transform --> 2-mode to 1-mode --> Rows. I have searched the documentation under packages 'sna', 'network', 'igraph', and

Hi all, I was installing a package *RBGL* of bioconductor. However, I had some issues while installing it. I asked the devel group of bioconductor and they told me to consult this group. Here is my conversation with the bioconductor group related to the problem *Me->* I was trying to install the RBGL package using the following command biocLite("RBGL") However, I got the

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, Has anyone run any R vs Python (numpy) tests? I'd love to see what the differences performance-wise are, specially handling large sparse matrices. Since both rely on external C code, there might not be much of a difference. If you know and use both languages, what are the main differences and what made you stick to one over another? I also noticed that there are strong libraries
