# ecolottery - Backward- and forward-in-time simulation of ecological communities [](https://www.gnu.org/licenses/gpl-3.0) [](https://cran.r-project.org/package=ecolottery)  [](https://travis-ci.org/frmunoz/ecolottery) [](https://ci.appveyor.com/project/frmunoz/ecolottery) 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, named *coalesc*. The package also includes a forward-in-time simulation algorithm, named *forward*, 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 the *coalesc* function for intensive simulation of biodiversity parrtterns in ABC analyses. ## Installing the package The version 1.0.0 is available on CRAN, https://cran.r-project.org/web/packages/ecolottery/index.html ```r install.packages("ecolottery") ``` The development version on Github can be installed using the `devtools` package: ```r devtools::install_github("frmunoz/ecolottery/pkg", build_vignettes = TRUE) ``` ## How to use the package The two main functions of the package are `coalesc()` and `forward()`. You can learn more on how to use them by looking at the [introduction vignette](pkg/vignettes/coalesc_vignette.Rmd). If you want to see how `coalesc_abc()` allows estimating parameters of community assembly with the ABC approach, have a look at the [Barro Colorado vignette](pkg/vignettes/Barro_Colorado.Rmd).
