...e 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 graphAM graph with undirected edges Number of Nodes = 4 Number of Edges = 5 how can I plot the object graph1?

Hello, Does anyone know of a way of finding all the nodes that are between a pair of specified nodes in the excellent graph package (R vers 2.5.0). I have a class(graphAM) object and need to determine all possible pathways in this object. Here's an example: In the simple case of a--b--c (where -- denotes "conected to") the list of all pathways would be: ab ba abc cba cb bc. Thanks in advance, Dan

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, I'm trying to create a connectivity diagram using RgraphViz library. I want to increase the edge's label fontsize, but the size did not change. Did I do something wrong ?

The bulk is on my forums - the final post for today is: Results to date: A. It looks like I am going to need a newer compiler for C - xlc/xlC V11 apparently does not understand this code: "/data/prj/cran/R-3.2.3/src/main/memory.c", line 2149.31: 1506-046 (S) Syntax error. I will have to check if R-devel has different code before asking for assistence. +2139 #ifdef
