[R] Advice on visual graph packages

[Gabor Csardi]

Jarrett, 

check the gplot function in package SNA and the plot.igraph and 
tkplot functions in package 'igraph'. SNA's gplot is more flexible,
it knows different shapes, edges can be curved, etc, tkplot is interactive
if you desire that. It is also easy to convert between the two
graph representations of the two packages, see the graph.adjacency and
get.adjacency function in igraph.
