adj-methods {graph} | R Documentation

## Methods for finding the adjacency list for selected nodes.

### Description

This generic function takes an object that inherits from the `graph` class and a node in that graph and returns a vector containing information about all other nodes that are adjacent to the given node. This means that they are joined to the given node by an edge. The accessibility list, `acc` is the list of all nodes that can be reached from a specified node.

### Value

The methods return vector of nodes that are adjacent to the specified node.

### Methods

object = graph

  An object that inherits from glass `graph`

index

  An index (could be multiple) which can be either the integer offset for the node(s) or their labels.

### Examples

     set.seed(123)
     gR3 <- randomGraph(LETTERS[1:4], M<-1:2, p=.5)
     adj(gR3, "A")
     adj(gR3, c(2,3))
