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 9
Here is the input file "input.txt" (a directed network with 10 nodes and 10
edges):
1 5
1 7
3 2
4 5
4 7
4 9
9 4
6 9
8 7
9 2
But the actual result is should be:
subcomponent(g, 4, "in"): 4 6 9
subcomponent(g, 4, "out"): 2 4 5 7 9
subcomponent(g, 4, "all"): 2 4 5 6 7 9
Why is the results computed by using the function subcomponent( ) different
from the actual result?
best
