Memory leak using Rgraphviz
...nstalled R 2.10.1 through the package manger. I then installed Rgraphviz 1.24 and graph 1.26 through R.
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 that reproduces the problem:
foo <- function () {
library(Rgraphviz)
set.seed(123)
V <- letters[1:26]
M <- 1:2
g1 <- randomGraph(V, M, 0.5)
edgemode(g1) <- "directed"
x <- layoutGraph(g1,name="foo",layoutT...

[Fwd: Re: controlling the edge linewidth in Rgraphviz]
Hi Adrian,
even better would be this:
1.) Install the latest Rgraphviz devel version
2.) Use the new API for graph rendering:
library(Rgraphviz)
example(randomEGraph)
x <- layoutGraph(g1)
graph.par(list(edges=list(lwd=2))) # if you want to set lwd=2 for the
whole session
# or if you just want to change this for your one graph:
renderGraph(x, graph.pars=list(edges=list(lwd=2)))
There is a Vignette that explains all the new stuff.
