[BioC] fontsize in Rgraphviz

[Mark W Kimpel]

I would like to vary the font size of node labels in Rgraphviz as I have 
been varying node size by fold change magnitude. Unfortunately, many 
attempts have failed and I continue to get the same font size. Here is 
my code followed by sessionInfo()

nAttrs$fontsize<-floor(22 * nodeWidth)

nodeWidth is a vector of widths which vary by node according to fold 
change. This works nicely, but font size does not.

help?

thanks,
Mark
