abstract: Provides a unified interface to download, harmonise and extract a wide range
  of environmental and socio-economic variables from established open data web services
  (such as 'WorldClim' <https://www.worldclim.org/>, 'CHELSA' <https://chelsa-climate.org/>
  and 'Bio-ORACLE' <https://www.bio-oracle.org/>, among others) for use in macroecology
  and biogeography. The package handles spatial subsetting to a study area, reprojection
  to a common coordinate reference system, and extraction of values at sampling points,
  so that predictors from heterogeneous sources can be assembled within a single reproducible
  workflow. Helper functions for collinearity checking and variable exploration are
  also included.
