generate.ESF

This function generates community data under the standard neutral model of biodiversity, using the urn scheme as described in Etienne 2005

A collection of sampling formulas for the unified neutral
model of biogeography and biodiversity. Alongside the sampling
formulas, it includes methods to perform maximum likelihood
optimization of the sampling formulas, methods to generate data given
the neutral model, and methods to estimate the expected species
abundance distribution. Sampling formulas included in the GUILDS
package are the Etienne Sampling Formula (Etienne 2005), the guild
sampling formula, where guilds are assumed to differ in dispersal
ability (Janzen et al. 2015), and the guilds sampling formula
conditioned on guild size (Janzen et al. 2015).
