Using Kjell's Graphviz recommendation, I modified the Rgraphviz package, now at version 1.20.1, in BioC 2.3. As far as I can tell, this new Windows binary package build of Rgraphviz is fully functional. Stealing liberally from the instructions on The RHugin Package Homepage, here are the step you need to install the new build of Rgraphviz in R-2.8.0: 1) Download and install Graphviz version 2.20.3. http://www.graphviz.org/pub/graphviz/stable/windows/graphviz-2.20.3.ms i 2) Add the location of the Graphviz binaries, the default being C:\Program Files\Graphviz 2.21\bin, to your PATH system environment variable. 3) Download and install the Rgraphviz package in R-2.8.0 using biocLite. source("http://bioconductor.org/biocLite.R") biocLite("Rgraphviz") Many, many thanks to Kjell Konis for pointing out the graphviz-2.20.3.msi distribution. I only needed to tweak a few configuration files to get the package to build properly. Patrick Theresa Scharl wrote: > Thank you very much for the information.
