Visualizing Networks With R

Arthur Charpentier shows off some of the functionality of igraph:

The good thing is that a lot of functions are available. For instance, we can get shortest paths between two specific nodes. And we can give appropriate colors to the nodes that we’ll cross:

> AP=all_shortest_paths(iflo,
+ from=”Peruzzi”,
+ to=”Ginori”)
> L=AP$res[[1]]
> V(iflo)$color=”yellow”
> V(iflo)$color[L[2:4]]=”light blue”
> V(iflo)$color[L[c(1,5)]]=”blue”
> plot(iflo)
