inla.CRSargs {INLA} | R Documentation

## Show expanded CRS arguments

### Description

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.

### Usage

    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.

### 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

### 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.

        print(fm_proj4string(crs1))
        print(fm_proj4string(crs2))
    }
