An R package implementing online methods for computing sufficient statistics of networks.
Online a few "local" statistics are implemented. Note that a small subset of network statistics are really feasible to do in an online fashion. For example, betweenness would be impossible.
The majority of this code came from the internals of ergm, written by the author of the statnet family of packages. Having these methods in a standalone package offers several benefits, though: 1) other network applications, 2) more easily extensible to new statistics, 3) possibly make ergm cleaner and easier for a wider community to understand and maintain.
NOTE: Update code only working for directed networks.
