drawing the graph with many nodes
Good morning,
I'm trying to draw a graph, and I'm using the following code.
test.matrix<-read.table("~/Desktop/Results/testgephi.csv", header = T,
sep=",")
colnames(test.matrix) <- gsub("X", "", colnames(test.matrix))
#drop first column
drops <- c("")
test.matrix<-test.matrix[,!(names(test.matrix) %in% drops)]

I'm trying to understand why a complex function my team wrote causes R's memory footprint viewed through top to increase every time it's run. I traced the increase in memory usage to layoutGraph() and wrote the following short function

+ c(0, 0, 1, 1),
+ c(1, 1, 0, 1),
+ c(1, 1, 1, 0))
> rownames(mat) <- colnames(mat) <- letters[1:4]

Nodes & edges with similarity matrix
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.

How to build a package which loads Rgraphviz (if installed)...
Dear List,

This is implemented as:

I'm new here, so this is my first try.
