R-CMD-check cran checks Downloads

R Classes and Methods for Spatial Data.

Before sp is loaded, options("sp_evolution_status") may be set to 0L for legacy behaviour, 1L for setting CRS(, doCheckCRSArgs=FALSE, ) and other minor steps to block calls out to rgdal etc., and 2L to use sf internally (not completed yet). If this option is not set, the environment variable _SP_EVOLUTION_STATUS_ can be used, again before sp is loaded, set to "0", "1" or "2"; this is used for running revdep checks under different evolution scenarios, anticipating retirement of maptools, rgdal and rgeos.
