[igraph] Root Directed Minimum Spanning Tree

[Alex Hayes]

Hey all,

I'm having some trouble getting a root direct minimum spanning tree in igraph. Currently I've got

library(igraph)

graph <- sample_pa(800)

ego_nodes <- ego(graph, nodes = 800, mode = "out")

# constructs a graph with nodes from root
# directed min spanning tree but too many edges
induced_subgraph(graph, ego_nodes[[1]])

Any advice?

Alex
