I have created an adjacency matrix but have not been able to figure something out. I need to put zeros on the diagonal of the adjacency matrix. For instance, location (i,i) to equal 0. Please help.

Dear all, Hi, I have the problems about converting the matrix to adjacency matrix.Here's my example, a b c d e fa 1.0000000 0.4048823682 0.1228531 0.49046991 0.4945158868 0.307443317b 0.4048824 1.0000000000 0.4367475 0.96949219 0.0007378596 0.560747765c 0.1228531 0.4367474719 1.0000000 0.40037341 0.3157538204

Dear all, how can I convert an m x n incidence matrix into an m x m adjacency matrix or an n x n adjacency matrix? The current matrix contains binary data, hence the new matrix would contain counts of common occurrences. Thank you for your help. Phil

Hello all, I'm having trouble creating an adjacency matrix. Basically, I need to turn the following distance matrix into an adjacency matrix based on whether values are >1.5 or not. If they are >1.5, then the returned value should be 0. If they are =<1.5, then the returned value should be 1. DistanceMatrix: A B C D E [1,]

Dear R community, is there an easy way to convert an adjacency list (or a data-frame) to a non-symmetric matrix? The adjacency list has the following form: person group 1 Sam a 2 Sam b 3 Sam c 4 Greg a 5 Tom b 6 Tom c 7 Tom d 8 Mary b 9 Mary d I need the data in a matrix with persons as rows and groups as columns: a b c d Sam 1 1 1 0 Greg 1 0 0 0 Tom 0 1 1 1 Mary 0 1 0 1 I know that there

...code is in a package, installed with R CMD INSTALL, and loaded with library(). I have tried to reduce the package to the bare minimum in order to discover the problem, but it continue even when reduced up to a single method, no dependency other than Matrix. The method is defined as: --- getAdjacentAsSparseMatrix <- function() { adjacents <- sparseMatrix(i=1:10, j=1:10, x=1:10) print(class(adjacents)); diagonal <- as.vector(diag(adjacents)); if (any(diagonal != 0)) { diagonal[diagonal > 1] <- 1; diag(adjacents) <- diagonal; }...

Dear R-help I am wondering if somebody wrote some code to convert an adjacency list model into a nested set model. In principal I want to do the same as John Celko mentioned it here with SQL: http://groups.google.co.uk/groups?hl=en&lr=lang_en&selm=8j0n05%24n31%241 %40nnrp1.deja.com Assume you have a tree structure like this Albert / \ /

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

Doesn''t appear to work with WEBrick. Works find with Apache/FastCGI. Something wrong in the way Rails is trying to process paths from the WEBrick server. If I try to send in http://localhost:3000/recipes/new, WEBrick is interpreting /new as my controller, instead of my action.

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 <-

Aloha all, I have an adjacency matrix for an acyclic digraph that contains transitive relations, e.g. (u,v), (v,w), (u,w). I want a DAG with only intransitive relations. Can someone point me to an R function that will take my adjacency matrix and give me back one with only intransitive relations? In the example, I'd like to get rid of (u,w) and keep (u,v) and (v,w). All the best, Tom --

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

Hi everyone, I am trying to apply linear regression to adjacent columns in a matrix (i.e. col1~col2; col3~col4; etc.). The columns in my matrix come with identifiers at the top of each column, but when I try to use these identifiers to reference the columns in the regression function using rollapply(), the columns are not recognised and the regression breaks do...

I'm looking for a way to do (product moment) graph correlation between multiple unlabeled graphs G to Gn. Basically I have 900 individual samples of a 48x48 adjacency matrix which I've listed as a 3rd dimension of a single array. So it looks something like [48,48,i] where i is each individual subject's adjacency matrix. If i run the gcor function on any two graphs for example
