Tools to create and modify network objects. The network class can represent a range of relational data types, and supports arbitrary vertex/edge/graph attributes.

The network package provides tools for creation, access, and
modification of network class objects. These objects allow for the
representation of more complex structures than can be readily handled by
other means (e.g., adjacency matrices), and are substantially more efficient
in handling large, sparse networks. While the full capabilities of the
network class can only be exploited by means of the various custom
interface methods (see below), many simple tasks are streamlined through the
use of operator overloading; in particular, network objects can often be
treated as if they were adjacency matrices (a representation which will be
familiar to users of the sna package). network objects are
compatible with the sna package, and are required for many packages
in the statnet bundle.
Basic information on the creation of network objects can be found by
typing help(network). To learn about setting, modifying, or deleting
network, vertex, or edge attributes, see help(attribute.methods).
For information on custom network operators, type
help(network.operators); information on overloaded operators can be
found via help(network.extraction). Additional help topics are
listed below.
