Download and Process Environmental Variables R package envar version 0.1.0 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.
