coenocliner {coenocliner} | R Documentation |
A coenocline simulation package for R
Description
coenocliner provides a simple, easy interface for simulating species abundance (counts) or occurrence along gradients.
Details
One of the key ways quantitative ecologists attempt to understand the properties and behaviour of the methods they use or dream up is through the use of simulated data. coenocliner is an R package that provides a simple interface to coenocline simulation.
Species data can be simulated from a number of species response models
Gaussian response
Generalised Beta response
and random count or occurrence data can be simulated from suitably parameterised response models by using the output from the response model as the mean or expectation of one of a number of statistical distributions
Poisson
Negative Binomial
Bernoulli
Binomial
Beta-Binomial
Zero-inflated Poisson (ZIP)
Zero-inflated Negative Binomial (ZINB)
Zero-inflated Binomial (ZIB)
Zero-inflated Beta-Binomial (ZIBB)
from which random draws are made.
