[R] Plotting with Rgraphviz

[slipkid90515]

Hi All,

After a lengthy battle just to get the package installed, I am not able to
actually use Rgraphviz to generate any plots.  I tried just using the sample
code in the documentation
(http://www2.warwick.ac.uk/fac/sci/moac/people/students/peter_cock/r/rgraphviz/)
and I get the following:

*> > library(Rgraphviz)
> test.matrix<-matrix(rep(c(0,1,0,0), 9), ncol=6, nrow=6)
> rownames(test.matrix)<-c("a", "b", "c", "d", "e", "f")
> colnames(test.matrix)<-c("a", "b", "c", "d", "e", "f")
> test.matrix
  a b c d e f
a 0 0 0 0 0 0
b 1 0 1 0 1 0
c 0 0 0 0 0 0
d 0 1 0 1 0 1
e 0 0 0 0 0 0
f 1 0 1 0 1 0
> am.graph<-new("graphAM", adjMat=test.matrix, edgemode="directed")
> am.graph
A graphAM graph with directed edges
Number of Nodes = 6 
Number of Edges = 9 
> plot(am.graph, attrs = list(node = list(fillcolor = "lightblue"),
+                                 edge = list(arrowsize=0.5)))

Anyone with the same problem?  Any ideas on how to fix?

Thanks,
Jess
