[R] naive help with setting node attributes

[adlai burman]

I have been trying for a LONG time to figure out how to do what I 
imagine is a fairly simple graph rendering issue. Can anyone help me 
figure out how to take two LARGE graphs G1 and G2 (not random) and set 
their node/edge attributes separately and uniquely such that when they 
are joined, G1 and G2 will retain their unique attributes under 
rendering?

Thanks,
AJ
