Rgraphviz alternative (was Re: Rgraphviz installation problem)

Some users of Rgraphviz may be interested in the new Bioconductor package "gaggle".

It presents possibly fewer installation problems, and provides access to
interactive graph display and manipulation from R via the Cytoscape program.  

Installation instructions may be found at

  http://gaggle.systemsbiology.org/docs/geese/r/

Click on the 'Mac OSX' link to the left on this page.

The vignette describes how to broadcast a network from R to Cytoscape:
