BIEN_ranges_shapefile_to_skinny function

Extract range data and convert to smaller "skinny" format

BIEN_ranges_shapefile_to_skinny converts ranges to a "skinny" format to save space.

BIEN_ranges_shapefile_to_skinny(directory, raster, skinny_ranges_file = NULL)

Arguments

• directory: The directory where range shapefiles will be stored. If NULL, a temporary directory will be used.
• raster: A raster (which must have a CRS specified) to be used for rasterizing the ranges.
• skinny_ranges_file: A filename that will be used to write the skinny ranges will be written to (RDS format). If NULL, this will not be written.

Returns

Matrix containing 2 columns: 1) Species name; and 2) the raster cell number it occurs within.

+units=m +no_defs +ellps=WGS84 +towgs84=0,0,0",
           extent = terra::ext(c(-5261554,5038446,-7434988,7165012 )),
