[BioC] Example of converting graphNEL object to ajacency matrix?

[Zembower, Kevin]

I'm interested in converting the graphNEL objects in the package SNAData
into adjacency matrices, so that I can convert them into 'network'
objects and use the R package 'sna' to analyze them. I'm working through
the examples in Wasserman and Faust, Social Network Analysis, and these
datasets will save me considerable typing.

I think that this is possible because of references to the 'coerce'
method on the graphNEL-class and graphAM-class help pages, but I haven't
been successful. I've tried commands like:
coerce(friendship, fs-mat)
coerce(friendship, fsmat)
as.matrix(friendship)
as.graphAM(friendship)
coerce(from="friendship", to="fsmat")

Can anyone give me an example of converting a graphNEL object to a
regular matrix, such as an adjacency matrix? I think with just one
example, I could work things out.

Thanks for your advice and suggestions.
