The ibis.iSDM package provides a series of convenience functions to fit integrated Species Distribution Models (iSDMs). With integrated models we generally refer to SDMs that incorporate information from different biodiversity datasets, external parameters such as priors or offsets with respect to certain variables and regions. See Fletcher et al. (2019) and Isaac et al. (2020) for an introduction to iSDMs.
The latest version can be installed from GitHub. A CRAN release will eventually be planned.
Note that the package is in active development and individual functions might change.
