Convert a vertex or edge sequence to an ordinary vector

Convert a vertex or edge sequence to an ordinary vector

Usage
as_ids(seq)

# S3 method for igraph.vs as_ids(seq)

# S3 method for igraph.es as_ids(seq)

Arguments
seq

The vertex or edge sequence.

Details

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.

Value

A character or numeric vector, see details below.
