[BioC] problems loading the Rgraphviz package

[Martin Morgan]

Hi --

The Rgraphviz currently available for Windows with biocLite is built
with graphviz 2.16, so you'll need to install

http://www.graphviz.org/pub/graphviz/ARCHIVE/graphviz-win-2.16.1.bin.tar.gz

Likely the problem you have below is because the path to graphviz
needs to be added to your system PATH variable, e.g., settings -> control
panels -> system -> advanced -> Environment Variables and then adding
or editing a variable PATH to contain the path to graphviz' bin
directory. My path reads in part

C:\Program Files\Graphviz2.16\Bin

The version of graphviz installed on your computer has to match the
version used to build Rgraphviz, so 2.18 will not work.
