similar to: Function for extracting Lambda Sets

Dear all, I am trying to run the function "lambdaSets" using the package "RBGL". This package uses another package "graph" which has been removed from the CRAN repository, but is available at the archive (http://cran.r-project.org/src/contrib/Archive/graph/). I installed the package from the R menu at "install packages from local zip files" (after

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

Hello R Help Team, I have created graph from weighted adjecency matrix .Is there a way I can find highly connected nodes in Igraph like the Package RBGL does. nathan -- View this message in context: http://www.nabble.com/Highly-Connected-Nodes-in-Igraph-tp22377522p22377522.html Sent from the R help mailing list archive at Nabble.com.

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.

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

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

Hello, I'm running an algorithm for graph structural cohesion that requires a depth-first search of subgraphs of a rather large network. The algorithm will necessarily be redundant in the subgraphs it recurses to, so to speed up the process I implemented a check at each subgraph to see if it's been searched already. This algorithm is very slow, and takes days to complete on a

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

Good afternoon, do you know if R provides a special package to make networks ? Thank you, Angela

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

Dear R Users, I have three questions. 1) Is there a way to get the output tex file to include \documentclass{report} \begin{document} and \end{document} so I can generate a PDF straight away. (I am trying to generate hundreds of these and don't want to have to manually type this in every time I load a tex file). 2) When I have have a table of greater than 9 columns, the columns to

Hello, I apologise if someone has already answered this but I searched and googled but didn't find anything. I have a matrix which gives me the similarity of each item to each other. I would like to turn this matrix into something like what they have in the graph package with the nodes and edges. http://cran.r-project.org/doc/packages/graph.pdf . However I cannot find a method to

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 everyone, I am an italian student who is working with packages SNA (social network analysis) and network. I ask you if there is a simple way to write a R-script using these packages to extract from an adjacency matrix the following things: -number of cliques which are in the network; -number of k-cores (e.g. 3-cores, 4-cores); -cycles (e.g. 3-cycles, 4-cycles) -hub & authorities.

Hi all, I am rather new to R. Recently I have been trying to implement some tree algorithms in R. I used lists to model tree nodes. I thought something like this would work: parent <- list(); child <- list(); parent$child1 <- child; child$parent <- parent; When I tried to check whether a node is its parent's first child using "if

Hi, I created the barchart below using the lattice package, however I can't seem to find a way to add another variable as a line (see the desired square/lines that I drew for the last 10 years of the plot). Can anyone help me with this? Your help is much appreciated! Code: Schart<-barchart(Catch~Year,data=SNA, scales=list(col = "black", tck = c(1, 0),x=list(rot=45)))
