Re: [igraph] About colors in communities plots

[Charles Novaes de Santana]

Thanks a lot!

so, to do exactly like the plot.communities does, I just need to "add"
transparency to the colors of the shadows, like this:

karate<-graph.famous("Zachary");
wc<-fastgreedy.community(g)
plot(wc, karate, colbar=c("#FF0000", "#00FF00",
"#FFFF00"),mark.col=c("#FF000055", "#00FF0055", "#FFFF0055"))

still simple, still beautiful! Very good!

All the best,

Charles
