[BioC] hyperdraw: How can I control node label font size?

[Paul Murrell]

Hi

This is a bug (or "missing feature") in 'hyperdraw'.
I will update the package with a fix, but in the meantime, does this 
workaround do what you want ?

pushViewport(viewport(gp=gpar(cex=.5)))
plot(testrabph, newpage=FALSE)
