Works perfectly!

Except:

library(Rgraphviz)
set.seed(123)
V <- letters[1:10]
M <- 1:4
g1 <- randomGraph(V, M, .2)
plot(g1, "neato")

Crashes R:

  *** caught bus error ***
address 0x0, cause 'invalid alignment'

Traceback:
1: .Call("Rgraphviz_doLayout", graph, as.integer(type), PACKAGE =  
"Rgraphviz")
2: layoutGraph(g)
3: agopen(x, name = name, layout = TRUE, layoutType = y, attrs =  
attrs,     nodeAttrs = nodeAttrs, edgeAttrs = edgeAttrs, subGList =  
subGList,     recipEdges = recipEdges)
4: .local(x, y, ...)
5: plot(g1, "neato")
6: plot(g1, "neato")


Possible actions:
1: abort (with core dump)
2: normal R exit
3: exit R without saving workspace
4: exit R saving workspace
