inla.spTransform {INLA}

R Documentation

Wrapper method for sp::spTransform

Description

Handles transformation of various inla objects accorting to coordinate reference systems of sp::CRS or inla.CRS class.

Usage

inla.spTransform(x, ...)

## Default S3 method:
inla.spTransform(x, crs0, crs1, passthrough = FALSE, ...)

## S3 method for class 'SpatialPoints'
inla.spTransform(x, CRSobj, passthrough = FALSE, ...)

## S3 method for class 'SpatialPointsDataFrame'
inla.spTransform(x, CRSobj, passthrough = FALSE, ...)

## S3 method for class 'inla.mesh.lattice'
inla.spTransform(x, CRSobj, passthrough = FALSE, ...)

## S3 method for class 'inla.mesh.segment'
inla.spTransform(x, CRSobj, passthrough = FALSE, ...)

## S3 method for class 'inla.mesh'
inla.spTransform(x, CRSobj, passthrough = FALSE, ...)

Arguments

x	The object that should be transformed from it's current CRS to a new CRS
...	Potential additional arguments
crs0	The source sp::CRS or inla.CRS object
crs1	The target sp::CRS or inla.CRS object
passthrough	default FALSE. Setting to TRUE allows objects with no CRS information to be passed through without transformation.
CRSobj	The target sp::CRS or inla.CRS object

Details

inla.spTransform.default Low level transformation of raw coordinates.

Value

The object is returned with its coordinates transformed

        crs = inla.CRS("longlat")
    )
    mesh2 <- inla.spTransform(mesh1, inla.CRS("lambert"))
    summary(mesh1)
    summary(mesh2)
