==================== Installing Rgraphviz ==================== Windows ======= Install an Rgraphviz binary package in the usual way Source based installation ========================= The Rgraphviz package depends on the Graphviz library which can be obtained from http://www.graphviz.org/. At present, Rgraphviz is known to work with Graphviz versions 2.2, 2.4, and 2.6. To install Graphviz: 1. Download the source tarball from http://www.graphviz.org/ 2. Unpack the distribution (tar -xzvf) 3. Read the Graphviz installation instructions. Basically, you should be able to do: ./configure make make install For the most recent version of Graphviz, you will also need to make sure that pkg-config (http://pkgconfig.freedesktop.org/wiki/) is installed on your system. If you install Graphviz to a non-standard location, you may need to set the PKG_CONFIG_PATH environment variable to tell pkg-config where the Graphviz metadata lives. Here is an example: export PKG_CONFIG_PATH=/home/me/graphviz/lib/pkgconfig At this point you should be able to install Rgraphviz either via R CMD INSTALL or by starting R and using install.packages. Note that older versions of Graphviz use a configure script called dotneato-config which must be in your PATH for Rgraphviz to find it. This is instead of the pkg-config setup.
