Is there an easy way to select all nodes that are within path length K of a certain node? So if K=1 it would be the node's
neighbours. If K=2 it would be the node's neighbours plus their neighbours' neighbours. The relevant nodes can of course be identified with the neighors() function as below but this gets very messy very quickly - is there a more direct way?
nodes <- c(neighbors(g,1), neighbors(g, neighbors(g,1)))
Thank you,
