create_biovar_stack: Create masked bioclimatic variable raster stack
In Vizzuality/vspt: Vizzuality tools for species distribution modelling

Description Usage Arguments Value Examples

Select historic and future bioclimatic variable rasters from directory, create ensembles, create a stacks, optionally convert to principle components and optionally mask by land. Note this function can take a while....

1 2	create_biovar_stack(region, biovar_list, scenario_list, time_interval_list, path, mask_by_land, pca_transform, use_future_pca)

`region`	String representing the region directory
`biovar_list`	List of string representing the biovar codes
`path`	String representing the path to the bioclimatic directory

A named list with the region as first level containing lists of; data file paths, processed historical and future biovariable rasters, polygon of land, the biovariable and scenario lists used, and optionally a pca model of the historical biovariables.
