R: Find the edge ids based on the incident vertices of the edges

get.edge.ids {igraph}

R Documentation

Find the edge ids based on the incident vertices of the edges

Description

get.edge.ids() was renamed to get_edge_ids() to create a more consistent API.

Usage

get.edge.ids(graph, vp, directed = TRUE, error = FALSE, multi = deprecated())

Arguments

graph

The input graph.

vp

The incident vertices, given as a two-column data frame, two-column matrix, or vector of vertex ids or symbolic vertex names. For a vector, the values are interpreted pairwise, i.e. the first and second are used for the first edge, the third and fourth for the second, etc.

directed

Logical scalar, whether to consider edge directions in directed graphs. This argument is ignored for undirected graphs.

error

Logical scalar, whether to report an error if an edge is not found in the graph. If FALSE, then no error is reported, and zero is returned for the non-existant edge(s).

multi
