Tools for Social Network Analysis

Description

sna is a package containing a range of tools for social network analysis. Supported functionality includes node and graph-level indices, structural distance and covariance methods, structural equivalence detection, p* modeling, random graph generation, and 2D/3D network visualization (among other things).

Details

Network data for sna routines can (except as noted otherwise) appear in any of the following forms:

Within the package documentation, the term "graph" is used generically to refer to any or all of the above (with multiple graphs being referred to as a "graph stack"). Note that usage of network objects requires that the network package be installed. (No additional packages are required for use of adjacency matrices/arrays or lists thereof.) In general, sna routines attempt to make intelligent decisions regarding the processing of multiple graphs, but common sense is always advised; certain functions, in particular, have more specific data requirements. Calling sna functions with inappropriate input data can produce "interesting" results.
