Rgraphviz 2.2.1 has been released as part of the Bioconductor 2.11 release.

Rgraphviz is an R interface to the Graphviz library (www.graphviz.org), which is used for graph layouts. Rgraphviz is one of the most popular packages from the Bioconductor project with more than 39,000 downloads in the last 12 months.

The major, user-visible change in Rgraphviz >= 2.x.x is that Rgraphviz no longer depends on an externally installed Graphviz. Instead it is bundled with a patched version of Graphviz 2.28.0. This should greatly simplify installation on all platforms (Linux, OS X and Windows, both 32 and 64 bit). It is now installed as any other Bioconductor package, simply by:
  R> source("http://www.bioconductor.org/biocLite.R")   R> biocLite("Rgraphviz")

In addition, numerous bugfixes to the Rgraphviz code has been incorporated.

This work could not have been completed without the generous help of numerous people. In alphabetical order (hopefully including all who have helped):
