Extract CRS information

Wrapper for CRS(projargs) (PROJ4) and CRS(wkt) for sp::Spatial objects.

inla.sp_get_crs(x)

Arguments

x

A sp::Spatial object

Value

A CRS object, or NULL if no valid CRS identified

Details

This function is a convenience method to workaround PROJ4/PROJ6 differences, and the lack of a crs extraction method for Spatial objects.
