Extract CRS information

Description

Use fmesher::fm_CRS() instead.

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

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

Usage

inla.sp_get_crs(x)

Arguments

Value

A CRS object, or NULL if no valid CRS identified
