fm_transform: Object coordinate transformation

In fmesher: Triangle Meshes and Related Geometry Tools

Object coordinate transformation

Description

Handle transformation of various inla objects according to coordinate reference systems of crs (from sf::st_crs()), fm_crs, sp::CRS or INLA::inla.CRS class.

Usage

fm_transform(x, crs, ...)

## Default S3 method:
fm_transform(x, crs, ..., crs0 = NULL)

## S3 method for class 'NULL'
fm_transform(x, crs, ...)

## S3 method for class 'matrix'
fm_transform(x, crs, ..., passthrough = FALSE, crs0 = NULL)

## S3 method for class 'sf'
fm_transform(x, crs, ..., passthrough = FALSE)

## S3 method for class 'sfc'
fm_transform(x, crs, ..., passthrough = FALSE)

## S3 method for class 'sfg'
fm_transform(x, crs, ..., passthrough = FALSE)

## S3 method for class 'Spatial'
fm_transform(x, crs, ..., passthrough = FALSE)

## S3 method for class 'fm_mesh_2d'
fm_transform(x, crs = fm_crs(x), ..., passthrough = FALSE, crs0 = fm_crs(x))

## S3 method for class 'fm_lattice_2d'
fm_transform(x, crs = fm_crs(x), ..., passthrough = FALSE, crs0 = fm_crs(x))

## S3 method for class 'fm_segm'
fm_transform(x, crs = fm_crs(x), ..., passthrough = FALSE, crs0 = fm_crs(x))

## S3 method for class 'fm_list'
fm_transform(x, crs, ...)

## S3 method for class 'inla.mesh'
fm_transform(x, crs = fm_crs(x), ...)

## S3 method for class 'inla.mesh.lattice'
fm_transform(x, crs, ...)

## S3 method for class 'inla.mesh.segment'
fm_transform(x, crs, ...)

Arguments

x	The object that should be transformed from it's current CRS to a new CRS
crs	The target crs object
...	Potential additional arguments
crs0	The source crs object for spatial classes without crs information
passthrough	Default is FALSE. Setting to TRUE allows objects with no CRS information to be passed through without transformation. Use with care!

Value

A transformed object, normally of the same class as the input object.

  rbind(c(0, 0), c(0, 90)),
  crs = fm_crs("sphere"),
  crs0 = fm_crs("longlat_norm")
)
