Generate directed Erdos-Renyi random networks with at least 1 basal node and only one component

This uses the igraph's function sample_gnm to generate nsim random networks with the same number of nodes and links than the parameter ig and two restrictions:

Usage

generate_er_basal(ig, nsim = 1000)

Arguments

ig

igraph object with parameters to use in the random network simulations: number of species/nodes and number of links/edges

nsim

number of simulations

Value

a list with igraph objects

Details

1. at least one basal species/node, that is a species that has no prey.

2. only 1 connected component so there is no disconnected species or sub-community.

Examples

generateERbasal(netData[[1]])
