R Documentation

Generates a GGM small-world network.

Description

Simulates a GGM as described by Yin and Li (2011), using the Watts and Strogatz (1998) algorithm for generating the graph structure (see watts.strogatz.game).

Usage

genGGM(Nvar, p = 0, nei = 1, parRange = c(0.5,1), constant = 1.5, propPositive = 0.5,
  clusters = NULL, graph = c("smallworld","random", "scalefree", "hub", "cluster"))

Arguments

`Nvar`	Number of nodes
`p`	Rewiring probability if graph = "smallworld" or "cluster", or connection probability if graph = "random". If cluster, can add multiple p's for each cluster, e.g., "c(.1, .5)"
`nei`	Neighborhood (see `watts.strogatz.game`).
`parRange`	Range of partial correlation coefficients to be originally sampled.
`constant`	A constant as described by Yin and Li (2011).
`propPositive`	Proportion of edges to be set positive.
`clusters`	Number of clusters if graph = "cluster"
`graph`	Type of graph to simulate
