This directory contains the 0-level adminstrative border of South Africa as a shapefile.
The file is used by dggridR for demonstrating how a shapefile can be used to produce a grid which overlays, for example, a country, or any other geolocated polygon.
The file was drawn from freely available data at:
http://www.diva-gis.org/gdata
I have used "http://www.mapshaper.org/" to simplify the shapefile in order to reduce the file size.
Any scripts or data that you put into this service are public.
