Hello!I am trying to use the subcomponent() to find the in-component and out-component from a given vertice.Here is the source code and result:> g<-read.graph("input.txt", "edgelist")
> subcomponent(g, 4, "in")[1] 4> subcomponent(g, 4, "out")[1] 4 3> subcomponent(g, 4, "all")[1] 4 3 10 5 7 6 8 2 9Here is the input file "input.txt" (a directed network with 10 nodes and 10 edges):1 51 73 24 54 74 99 46 98 79 2But the actual result is should be:subcomponent(g, 4, "in"): 4 6 9subcomponent(g, 4, "out"): 2 4 5 7 9subcomponent(g, 4, "all"): 2 4 5 6 7 9Why is the results computed by using the function subcomponent( ) different from the actual result?bestXueming
