Hi Paul
Rgraphviz is a bioconductor package, so ask on the Bioconductor mailing
list.
http://bioconductor.org/docs/mailList.html
Install Bioconductor packages following the instructions here
http://bioconductor.org/docs/install/
Rgraphviz on Windows installed from binary (as you're doing below)
requires that your computer has the same version of graphviz as the
computer used to build Rgraphviz. The details are in the package README
file (inconveniently linked from here
http://bioconductor.org/packages/2.5/bioc/html/Rgraphviz.html
at
http://bioconductor.org/packages/2.5/bioc/src/contrib/Rgraphviz_1.24.0.tar.gz
Cutting and pasting from this file, the instructions are:
o. install Graphviz ***2.20.3.1*** Windows ***binary*** distribution from
http://www.graphviz.org/pub/graphviz/stable/windows/graphviz-2.20.3.1.msi
in a directory that we'll call $DIR. We use the following as an example:
C:\Graphviz2.20
If you install it in other dir, just use your dir correspondingly.
o. Add Graphviz' bin diretory to the user PATH variable, e.g.,
c:\Graphviz2.20\bin
o. Check the configuration by starting a new DOS window and displaying
the PATH environment variable, e.g.,
c:\> echo %PATH%
o. Use biocLite('Rgraphviz') to install Rgraphviz
