Re: [igraph] Question on layout.drl .... What are the colors?

[Gábor Csárdi]

Peter,

vertex colors are used if the 'color' vertex attribute is present.
Edge colors are used if the 'color' edge attribute is present. Supply
'NA' to 'edge.color' and/or 'vertex.color' if you want to suppress the
'color' vertex/edge attribute.

Details are in ?igraph.plotting.
