isAdjacent-methods {graph} | R Documentation

## Determine if nodes share an edge in a graph

### Description

For a given subclass of `graph-class`, returns `TRUE` if the graph contains an edge from node specified by `from` to the node specified by `to`.

The appropriate logical vector will be returned as long as `from` and `to` have the same length and contain nodes in the graph object specified by `object`.

### Usage

    isAdjacent(object, from, to, ...)

### Arguments

`object` | An instance of a subclass of `graph-class`.
`from` | A `character` vector of nodes in the graph.
`to` | A `character` vector of nodes in the graph
`...` | May be used by methods called on subclasses of `graph`
