[BioC] Changing fontsize in Rgraphviz

[michael watson (IAH-C)]

Hi

I think I am probably being a complete idiot, but I can't change the
fontsize in simple Rgraphviz plots:

library("Rgraphviz")
set.seed(123)
V <- letters[1:10]
M <- 1:4
g1 <- randomGraph(V, M, 0.2)

plot(g1)

plot(g1, attrs=list(node = list(fontsize="80")))

Both of these produce the same plot, with no change in fontsize.  I'm
probably using the attributes incorrectly, so please someone put me out
of misery and show me!

Please don't ask me to upgrade Rgraphviz - I need this version to work
with my version of graphviz
