Hi, I am using R-2.0 and trying to do: > install.packages2("Rgraphviz",develOK = TRUE); I have graphviz version 1.12 installed from AT&T website. I get below output: > install.packages2("Rgraphviz",develOK = TRUE); Note: You did not specify a download type. Using a default value of: Source This will be fine for almost all users [1] "Attempting to download Rgraphviz from http://www.bioconductor.org/repository/devel/package/Source" [1] "Download complete."

> Warning messages: > 1: Undefined slot classes in definition of "Ragraph": > boundBox (class " boundingBox ") in: > .completeClassSlots(ClassDef, where) <snip other="" warnings=""> These are from the order of the file collation but don't really have any ill effect with the package usage. There are actually quite a few packages running around w/ these sorts of warnings, I fix them when I find them.
