similar to: correlation between multiple adjacency matrix graphs

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

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 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 / \ /

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

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

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 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

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 <-

Hi Giang, Given that the community deprecated the Alpha backend, I'm doubtful anyone would be able to point you in the right direction. Have you iteratively tried the difference versions of LLVM (i.e., 2.9, 2.8, 2.7 on down the line)?

Thanks Andrew. I would like to clarify what I tried to do. I want to use llvm-gcc on x86 linux to compile C programs into Alpha binary.

llvm-gcc doesn't not compile *on* alpha (128bit fp and int issues). I haven't tried it as a cross compiler.

Hi, For my work, I want to use LLVM to compile SPEC 2k for Alpha. Since Alpha support has been dropped, I tried using version 2.8, but it is quite buggy, probably because the Alpha backend has not been maintained. I was wondering if there is an earlier version where the Alpha backend is stable enough to compile SPEC 2k? For my purpose, I do not need the most advanced optimizations, so an

Hi, I wonder if anyone has been able to successfully build llvm-gcc as an Alpha cross compiler? I have tried many different combinations of flags and gcc compiler, but have not been able to build successfully. Currently, this is the command that I used to build on Ubuntu 10.10: ../llvm-gcc-4.2-2.8.source/configure --enable-llvm=/home/ghoang/research/llvm/llvm-objects --enable-languages=c,c++

Hi all; I have two vectors A=c(5,2,2,3,3,2) and B=c(2,3,4,5,6,1,3,2,4,3,1,5,1,4,6,1,4) and I want to make the following matrix using the information I have from the above vectors. 0 1 1 1 1 1 1 0 1 0 0 0 0 1 0 1 0 0 1 0 1 0 1 0 1 0 0 1 0 1 1 0 0 1 0 0 so the first vector says that I have 6 elements therefor I have to make a 6 by 6 matrix and then I have to read 5 elements from the

I have huge list of edges with weights. a1 b1 w1 a2 b2 w2 a3 b3 w3 a1 b1 w4 a3 b1 w5 I have to convert it into 2 dim matrix b1 b2 b3 a1 max(w1,w4) 0 0 a2 0 w2 0 a3 w5 0 w3 if edges repeated take the maximum weights. How do this efficiently without using for loop? Any idea. thanks Avi [[alternative
