make_grid creates a sf grid of polygons. The spatial
reference is taken from the spatial object.
make_grid(spobj, width, height = width, polygon, crs = 4326, ...)
A spatial object of class sp or sf or a Character. When it is a character, it is assumed that it is a path to wrfinput file to create a grid class 'sf' based on this file. This is done by running eixport::wrf_grid.
Width of grid cell. It is recommended to use projected values.
Height of grid cell.
coordinate reference system in numeric format from http://spatialreference.org/ to transform/project spatial data using sf::st_transform. The default value is 4326
