Description: Collection of R functions to do purely presence-only species
    distribution modeling with isolation forest (iForest) and its
    variations such as Extended isolation forest and SCiForest. See the
    details of these methods in references: Liu, F.T., Ting, K.M. and
    Zhou, Z.H. (2008) <doi:10.1109/ICDM.2008.17>, Hariri, S., Kind, M.C.

    Additionally, Shapley values are used to explain
    model inputs and outputs. See details in references: Shapley, L.S.

    (2014) <doi:10.1007/s10115-013-0679-x>. itsdm also provides functions
    to diagnose variable response, analyze variable importance, draw
    spatial dependence of variables and examine variable contribution. As
    utilities, the package includes a few functions to download
    bioclimatic variables including 'WorldClim' version 2.0 (see Fick,
    S.E. and Hijmans, R.J. (2017) <doi:10.1002/joc.5086>) and
    'CMCC-BioClimInd' (see Noce, S., Caporaso, L. and Santini, M. (2020)
