[BioC] Rgraphviz and margins

[Robert Stojnic]

Hello,

I am using Rgraphviz, first by calling layoutGraph() then renderGraph() 
on graphNEL. However, I cannot get the graph to be rendered with certain 
margins. I've tried the oldfashioned par(mar=...), tried passing the 
margin parameters to both layoutGraph and renderGraph, but nothing 
worked. The plot always take all the available area. Setting outer 
margins does work (with par), but breaks in the context of multiple 
plots per page.

Anyone know how to set margins in Rgraphviz?

Cheers, Robert
