Hi, I've got two issues. (1) I tried to replicate the Rgraphviz Vignette but crashed at plotting step. > library(Rgraphviz) Loading required package: graph Loading required package: grid > set.seed(123) > V <- letters[1:10] > M <- 1:4 > g1 <- randomGraph(V, M, 0.2) > g1 A graphNEL graph with undirected edges Number of Nodes = 10 Number of Edges = 16 > plot(g1) crashed here! As you can see below, I recently installed R v2.11.1 on Windows Vista. The graphviz is version 2.20.3.1 (quite an old one but Rgraphviz specifically mentioned this version). Any ideas? > sessionInfo() R version 2.11.1 (2010-05-31) i386-pc-mingw32 locale: [1] LC_COLLATE=English_Singapore.1252 LC_CTYPE=English_Singapore.1252 [3] LC_MONETARY=English_Singapore.1252 LC_NUMERIC=C [5] LC_TIME=English_Singapore.1252 attached base packages: [1] grid stats graphics grDevices utils datasets methods [8] base other attached packages: [1] Rgraphviz_1.26.0 graph_1.26.0 loaded via a namespace (and not attached): [1] tools_2.11.1 (2) If I want to use newer version of graphviz in *nix system (not the windows system), is there any hope for this or do I still need to stick to the version 2.20.3.1? Specifically, I have 64bit R-2.11 on Mac OS X 10.6 in mind. Thanks in advance, TH -- Tae-Hoon Chung, PhD [[alternative HTML version deleted]]

There is no specific reason for using a "new" version of Graphviz. Rgraphviz only uses part of the functionality from Graphviz, and I have not seen anything that indicates that the functionality actually used is significantly updated (I could be wrong of course). It is easy to use a newer version of Graphviz on *nix. If you cannot use the provided binary of Rgraphviz for Vista, you will need to compile Rgraphviz from source in which case you might be able to use a newer Graphviz (I have had reports of success with this). But all of this requires you to setup your windows box for building.
