Create a coordinate reference system object

in favour of fmesher::fm_CRS()

Creates either a CRS object or an inla.CRS object, describing a coordinate reference system.

inla.CRS(..., args = NULL)

inla.wkt_predef()

Arguments

...

Arguments passed on to fmesher::fm_CRS(...).

args

list of named proj4 arguments.

Value

Either an sp::CRS object or an inla.CRS object, depending on if the coordinate reference system described by the parameters can be expressed with a pure sp::CRS object or not.

An S3 inla.CRS object is a list, usually (but not necessarily) containing at least one element:

crs

The basic sp::CRS object

inla.wkt_predef returns a WKT2 string defining a projection

inla.wkt_predef returns a WKT2 string defining a projection

Functions

• inla.wkt_predef(): in favour of fmesher::fm_wkt_predef()
