[BioC] Rgraphviz: fail to plot

[HÃ¥vard Rue [guest]]

I upgraded Rgraphviz, and now it fails to plot even the first example,

> set.seed(123)
> V <- letters[1:10]
> M <- 1:4
> g1 <- randomGraph(V, M, 0.2)
> plot(g1)
Error in as.double(y) : 
  cannot coerce type 'S4' to vector of type 'double'

seems like no 'plot method' is defined for the graph; but this sounds like something else is going on. 

Anyone with a similar problem?
