#' island: Stochastic Island Biogeography Theory Made Easy
#'
#' Tools to develop stochastic models based on the Theory of Island Biogeography
#' (TIB) of MacArthur and Wilson (1967) and extensions. The package allows the
#' calculation of colonization and extinction rates (including environmental
#' variables) given presence-absence data, the simulation of community assembly
#' and model selection.
#'
#' @details In the simplest stochastic model of Island Biogeography, there is a
#' pool of species that potentially can colonize a system of islands. When we
#' sample an island in time, we obtain a time-series of presence-absence
#' vectors for the different species of the pool, which allows us to estimate
#' colonization (\eqn{c}) and extinction (\eqn{e}) rates under perfect
#' detectability. These are actual rates (in time^{-1} units). \cr The
#' simplest stochastic model of island biogeography assumes a single
#' colonization-extinction pair for the whole community. This model implicitly
#' assumes: first, neutrality of the species in the community, that is, all
#' species in the community share the same values for those rates; and second,
#' all species colonize and become extinct independently from each other. The
#' "species neutrality assumption" can be relaxed easily, for example,
#' calculating different rates for different groups or on a per-species basis.
#' In addition, we can make these rates depend on environmental variables
#' measured at the same time that we took our samples. For more information of
#' the basic model, please see the references.
#'
#' @section Data entry: The data should be organized in dataframes with
#' consecutive presence-absence data of each sample ordered cronologically,
#' being the data associated with a single species in a row. Additional
#' columns can contain the filiations of every species to a group, i. e. a
#' phylogenetic group or a guild.
