Download and Process Environmental Variables // 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.
