[R] Drawing a graph with vertices and edges using tcl/tk

Another approach is the Bell Labs graphviz system.  See


For an example of using it from R, see the dot.proto function
in the 'proto' package.  dot.proto generates dot language output 
to draw a graphviz graph of the objects in any R program written 
using 'proto'.

   # see ?dot.proto for instructions on displaying graph

The above approach should work on any OS supported by R
(since graphviz works on all of them); however, on UNIX one
could also use the Rgraphviz package that specifically
interfaces R with graphviz:
