The package allows quick and efficient simulation of community composition under diverse combinations of environmental filtering and neutral birth-death dynamics. The package offers a coalescent-based, backward-in-time algorithm, namedcoalesc.The package also includes a forward-in-time simulation algorithm, namedforward, to investigate a broader set of niche-based dynamics, albeit at the expense of greater resources and computation time.

coalesc_abc is another core function of the package, to perform Approximate Bayesian Computation (ABC) and infer parameters of the processes from observed community composition. This function relies on thecoalesc function for intensive simulation of biodiversity parrtterns in ABC analyses.

The version 1.0.0 is available on CRAN,https://cran.r-project.org/web/packages/ecolottery/index.html

install.packages("ecolottery")

The development version on Github can be installed using thedevtools package:

devtools::install_github("frmunoz/ecolottery/pkg",build_vignettes=TRUE)

The two main functions of the package arecoalesc() andforward(). You can learn more on how to use them by looking at theintroduction vignette.

If you want to see howcoalesc_abc() allows estimating parameters of community assembly with the ABC approach, have a look at theBarro Colorado vignette.
