# Methods to Simulate Networks from the Congruence Class Model.

### Description

CCMnet is a collection of methods to simulate networks from the Congruence Class Model (CCM) for networks. For details regarding CCM see the paper by Goyal et al. in the reference section below.

For a list of functions type: help(package='CCMnet')

.

### Details

The `CCMnet_constr`

function simulates networks based on the CCM for networks; see the examples section of the `CCMnet_constr`

function for a few demonstrations.

This package relies on the network package, which allows networks to be represented in **R**. Markov Chain Monte
Carlo methods are from the ergm package; CCMnet is partially based on C code from the ergm package (see reference by Handcock et al. below). The SNA package allows for additional methods relating to social network analysis. For detailed information regarding these packages go to the statnet website: http://statnet.org. This package incorporates an ergm-term coded by Nicole Bohme Carnegie (carnegie@hsph.harvard.edu).
