Hi Arber
Rgraphviz
http://bioconductor.org/packages/2.4/bioc/html/Rgraphviz.html
is one option; it can be tricky to install on Windows / Mac where the
version of graphviz installed on your system needs to be the same as the
version used to build the package. See the README file in the package
source distribution
http://bioconductor.org/packages/2.4/bioc/src/contrib/Rgraphviz_1.22.1.tar.gz
