r - How do I simply access the values of an "edge sequence" igraph object? -



r - How do I simply access the values of an "edge sequence" igraph object? -

i want access ids of vertices connected vertex u in graph g.

i utilize command e(g)[from(u)]. generates next output:

edge sequence:

[9814] 122 -> 24

[9815] 122 -> 178

[9816] 122 -> 124

how access values 24, 178, , 124?

i realise may simple command, cannot find out how anywhere in documentation.

maybe simplest utilize neighbors() function in first place:

neighbors(g, u, mode="out")

if want border sequence, then:

v(g)[ to(e(g)[from(u)]) ]
