Methods for Accessibility Lists
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 accessible from the given node. The
methods are vectorized so that index can be a vector.

object |
An instance of the appropriate graph class. |
index |
A character vector specifying the nodes for which accessibilty information is wanted. |
The methods should return a named list of integer vectors. The
names of the list correspond to the names of the supplied
nodes. For each element of the list the returned vector is named. The
names of the vector elements correspond to the nodes that are
accessible from the given node. The values in the vector indicate how
many edges are between the given node and the node in the return vector.
An object of class graph.
An instance of the clusterGraph
class.
A character vector of indices corresponding to nodes in the
graph.
