Classes and methods for spatial
data; the classes document where the spatial location information
resides, for 2D or 3D data. Utility functions are provided, e.g. for
plotting data as maps, spatial selection, as well as methods for
retrieving coordinates, for subsetting, print, summary, etc. From this
version, evolution status is set to '2L' using 'sf' in place of 'rgdal',
see for details.
Retiring packages 'maptools', 'rgdal' and 'rgeos' will be dropped by
