R: Incident edges of multiple vertices in a graph

incident_edges {igraph} | R Documentation

## Incident edges of multiple vertices in a graph

### Description

This function is similar to `incident`, but it queries multiple vertices at once.

### Usage

    incident_edges(graph, v, mode = c("out", "in", "all", "total"))

### Arguments

`graph` | Input graph.
`v` | The vertices to query
`mode` | Whether to query outgoing (‘out’), incoming (‘in’) edges, or both types (‘all’). This is ignored for undirected graphs.

### Value

A list of edge sequences.

### Examples

    g <- make_graph("Zachary")
    incident_edges(g, c(1, 34))
