| network-package {network} | R Documentation |
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.
