OK, I am on windows XP, I have R 2.7.2, graphviz 2.20.2 and Rgraphviz_1.18.1. My graphs are just blank windows! > library("Rgraphviz") > set.seed(123) > V <- letters[1:10] > M <- 1:4 > g1 <- randomGraph(V, M, 0.2) > > plot(g1) Produces just a simple, beautiful white window.... Am I using the wrong version of graphviz? Thanks Mick

i believe you will get a non-blank window if you back down the Rgraphviz version to the one distributed in bioconductor 2.1 (Rgraphviz 1.16.0) this installed and ran for me today on XP under R 2.7.2 -- take the zip file from the past bioc releases and install using the R GUI installer getting the current Rgraphviz to port to windows is not straightforward; various emails have covered this in recent months --- Vince Carey, PhD Assoc.
