Show expanded CRS arguments

Wrapper for sp::CRS and inla.CRS objects to extract the coordinate reference system argument string. 'r lifecycle::badge("deprecated")` in favour of fmesher::fm_proj4string(), or fmesher::fm_wkt() for WKT2 representations.

inla.CRSargs(x, ...)

inla.as.CRSargs.list(x, ...)

inla.as.list.CRSargs(x, ...)

inla.as.list.CRS(x, ...)

inla.as.CRS.list(x, ...)

Arguments

x

An sp::CRS or inla.CRS object (for inla.CRSargs and inla.as.list.CRS), a character string (for inla.as.list.CRSargs), or a list (for inla.as.CRS.list and inla.as.CRSargs.list).

...

Additional arguments passed on to other methods.

Value

For inla.CRSargs and inla.as.CRSargs.list, a character string with PROJ.4 arguments.

For inla.as.list.CRS and inla.as.list.CRSargs, a list of name/value pairs.

For inla.as.CRS.list, a CRS or inla.CRS object.

Details

• inla.as.CRSargs.list: CRS proj4 string for name=value pair list

• inla.as.list.CRSargs: List of name=value pairs from CRS proj4 string
