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

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.

Dear R users, I'm using graph library to create a mesh-like network topology and implement a load balance routing algorithm. The current implementation uses graph, RBGL, and Rgraphviz libraries. I have a few attributes on every edge to represent the network loading and capacity, and I frequently update these values. However, I found it works so slow and right now I'm consider rewriting it

Hi I've been trying to install RBGL and several other packages in gR task view on Fedora11 64 bit without success My guess is that it is due to boost (fedora is at boost 1.37 which is a few minor versions behind 1.40) and very recent g++ Has anyone managed to install the gR task view or RBGL in particular? Thanks Cheers Peter ======== [root at SPH-PH-428-04P ~]# gcc --version gcc (GCC)

Dear R community Hope all of you are fine. I have a question regarding the an error message. Actually, I am trying to generate classification trees using "tree" package. It works well but for some datasets e.g., wine, yeast, boston housing etc. it gives an error message. Error in tree(V14 ~ ., data = training.data, method = c("recursive.partitioning"), : maximum

Dear R community I have a question regarding the value of cost complexity parameter "k" used in "tree" package for pruning purpose. Any help in finding the optimum value of "k" is requested. Please give some suggestion in this regard. In the example below i used k=0 but i don't know why? But if i use k=NULL, then it will not plot the resultant tree.

I have a problem with running the tree package (dec.8, 2001) for R.

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.

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

Dear all, My gRbase package imports functionality from the bioconductor packages graph, Rgraphviz and RBGL. To make installation of gRbase easy, I would like to have these bioconductor packages installed in connection with installation of gRbase, but to do so the user must use setRepositories() to make sure that R also installs packages from bioconductor. Having to call setRepositories causes

Some time ago I had difficulty installing RBGL with Ubuntu Hardy on R-2.7.0 and the problem was attributed to an with BGL.

Dear all, I have the following problem: I have written a function genereating to plots, eg myfunction <- (data, some.parameters) { #some calculations etc . par (mfrow=c(1,2)) plot1(......) plot2(.....) } which works fine.

Hi, Li, Thanks for reply. It is strange that I used RBGL_1.6.0 successfully on the same linux system with R 2.3.1 before! After trying to install R 2.5.1, the RBGL_1.12.0 failed to be installed. Then, I uninstalled R. Delete the directory R/lib/. Installed R.2.3.1 again. And run getBioC1.8.5 for R 2.3.1 to download the three packages graph_1.10.6, RBGL_1.12.0 and Ruuid_1.10.0. But still
