[igraph] plot graph with color of nodes as node out-degree + colorbar

[Giulia Rossello]

Dear all,

I am trying to plot a graph using a color scale corresponding to node's out-degree.

Moreover, I would like to create a colorbar at the bottom of the plot for with the corresponding color scale of node's out-degree.

Here what I am doing:

#ALL

indegree<-degree(all, v = V(all), mode = c("in"))

outdegree<-degree(all, v = V(all), mode = c("out"))

V(all)$size <- indegree+2

V(all)$frame.color <- "white"

l<-layout_with_fr(all)

E(all)$arrow.size <- .09

E(all)$edge.color <- "gray80"

E(all)$width <- 1+E(all)$weight/max(E(all)$weight)

V(all)$color<-rainbow(length(outdegree))[rank(outdegree)]

pdf(paste(dr[1],year[1],"-",year[length(year)],field[1],"allnet.pdf"))

plot(all, layout=l,vertex.label=NA)

dev.off()

Do you have some suggestions?

Thank you in advance
