Description: A suite of tools to mitigate sampling bias in species occurrence
    records by thinning data in the environmental space (E-space). This process
    can improve the accuracy and precision of species distribution models (SDM,
    also known as ecological niche models, ENM). The package offers a
    data-driven protocol to determine thinning parameters using kernel-density
    bandwidth selection. Two thinning methods are provided (stochastic and
    deterministic) to reduce over-sampled environmental conditions and down-weight
    outlier observations. The name 'bean' reflects the core principle of the
    method: each 'pod' (a grid cell in E-space) is allowed to contain only a
    limited number of 'beans' (occurrence points). See Silverman (1986,
    ISBN:978-0-412-24620-3) and Rousseeuw and Leroy (2003,
    ISBN:978-0-471-48855-2) for the underlying statistical methods.
