seq

The vertex or edge sequence.

For graphs without names, a numeric vector is returned, containing the internal numeric vertex or edge ids.

For graphs with names, and vertex sequences, the vertex names are returned in a character vector.

For graphs with names and edge sequences, a character vector is returned, with the ‘bar’ notation: a|b means an edge from vertex a to vertex b.

A character or numeric vector, see details below.

g <- make_ring(10)
as_ids(V(g))
as_ids(E(g))

V(g)$name <- letters[1:10]
as_ids(V(g))
as_ids(E(g))
