Graph visualization
Hello, I am working with graph and adjacency matrix, the package 'graph' seems to be appropriate for this. An example in the package > mat <- rbind(c(0, 0, 1, 1), + c(0, 0, 1, 1), + c(1, 1, 0, 1), + c(1, 1, 1, 0)) > rownames(mat) <- colnames(mat) <- letters[1:4] > graph1 <- new("graphAM", adjMat=mat) > graph1 A

graph or svn
Hello all, I'm having a spot of trouble. I have made a very nice distance matrix from some comparison calculations. However, the matrix is 3096 x 3096, so it's relatively large. Currently I'm using the svn package as it seems to work for my data. The graph package errors and says the "adjacency matrix must be symmetric for undirected graphs". I though 3096 x 3096 was

[LLVMdev] Graph Utilities
Hi, I am wondering if there is any generic graph data structure along with its traversal routines already available in LLVM-2.7. In particular, I am looking for creating both directed and undirected graphs and be able to perform dfs, topsort, and scc on them. Best regards, Raj

Rgraphviz: How to control the colours of edges in a graph
Using Rgraphviz, I draw the undirected graph with vertices A,B,C and D and edges A:B, B:C, C:D, D:A, A:C. I want the vertices A and B to be red and C and D to be blue. The problem is the following: I want the edges A:B and B:C to be green and the edges C:D and C:A to be yellow, while the edge A:C can have the default colour black. I assume that I have to specify this using the edgeAttrs-argument

plot - kamada.kawai layout without arrows
Hi, I am plotting a graph with kamada.kawai layout. But I am getting direction arrows in the graphs. Please let me know how to avoid this. g <- watts.strogatz.game(1, 2000, 5, 0.4) comps <- clusters(g)$membership colbar <- rainbow(max(comps)+1) V(g)$color <- colbar[comps+1] png(filename) plot(g, layout=layout.kamada.kawai, vertex.size=2, vertex.label=NA) dev.off() Please find

connectivity measure for graph nodes
I am doing some work the Rgraphviz, a Bioconductor package, but since my question is of a more general nature, thought I would send to this list in hopes that a graph theory expert could answer my question. I wish to do some statistics on node-node relationships. In particular, I want to see if two connected nodes share a common property. I believe that the more "connected" the two

vectorizaton
Hi, I got 1000 NxN matrices grouped in one array. I want one matrix in which p_ij is the average of all the 1000 matrices in the array. Here's what I'm trying to do: # P is the NxNx1000 array for(i in 1:N) for(j in 1:N) for(k in 1: 1000) mymat[ i, j ] <- mean( P [i , j , k ] ) Otherwise, I could have a NxNx1000 vector, and get the N^2 means of the 1+ (N^2)*(0: 999) elements.

Any progress on undirected self-referential many to many relationships?
I am going to re-ask a question that has been asked a few times in the past. What is the best way to represent an undirected self-referential many to many relationship. Trivial examples of this include an edge in an undirected graph, or a mutual friendship. Alice is a person Bob is a person Alice and Bob are friends of each other We have a whole bunch of extra information about their friendship

Undirected to Directed Graph ( Clustering Based on Link Strength)
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

igraph o network
Estimados, estoy ?jugando? con unos datos clínicos donde realizo un análisis de redes, utilicé igraph como nerwork, pero finalmente uso igraph (creo que tiene más opciónes). Son algo de 200 nodos y algo más de 2000 relaciones. Puedo graficarlos. Los datos están de la siguiente forma, por ejemplo, individuo, patología, (las dos primeras columnas son la relación), luego un fármaco, el grupo

Need help on having multiple distributions in one graph
R-listers: I have searched the help files and everything I have related to R graphics. I cannot find how to graph y against several distributions on a single graph. Here is code for creating 4 Poisson distributions with different mean values, although I would prefer having it in a loop: The top of the y axis for the first distribution, with count of 0, is .6, which is the highest point for

superimposing network graphs
Dear all, I have a undirected network (g), representing all the sexual relationships that ever existed in a model community. I also have a directed edgelist (e) which is a subset of the edgelist of g. e represents the transmission pathway of HIV. Now I would like to superimpose the picture of the sexual relationships with arrows in a different colour, to indicate where in the network HIV was

[LLVMdev] tbaa metadata representation
Hi all, A while ago there was a discussion on changing the current "set of trees" representation of TBAA metadata to be more expressive, prompted by the need to support C structs. Dan Gohman also talked about the issue here: http://llvm.org/devmtg/2012-11/Gohman-AliasAnalysis.pdf. It was suggested that the trees be replaced by a type DAG then. While working on this compiler

The network printers begin to refuse access. And then I noticed that the workstations begin to refuse access too. smb.conf --- [global] netbios name = OBLR workgroup = X125 server
