[R-pkgs] Rgraphviz 2.2.1

[Kasper Daniel Hansen]

(cross-posted to Graphviz-devel)

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):
