R folks: this is my first posting, so please forgive me if i have missed something on this in the archives or other documentation. I have been trying to use gplot to draw a network diagram. can anyone suggest a method to minimise the number of edges that cross? do i need to use the stringrepulse mode and tweak some of the parameters?
