fm_transform: 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, fm_CRS, or INLA::inla.CRS class.

Usage

fm_transform(x, crs, ...)
# S3 method for default
fm_transform(x, crs, ..., crs0 = NULL)
## S3 method for class 'NULL'
fm_transform(x, crs, ...)
# S3 method for matrix
fm_transform(x, crs, ..., passthrough = FALSE, crs0 = NULL)
# S3 method for sf
fm_transform(x, crs, ..., passthrough = FALSE)
# S3 method for sfc
fm_transform(x, crs, ..., passthrough = FALSE)
# S3 method for sfg
fm_transform(x, crs, ..., passthrough = FALSE)
# S3 method for Spatial
fm_transform(x, crs, ..., passthrough = FALSE)
# S3 method for fm_mesh_2d
fm_transform(x, crs = fm_crs(x), ..., passthrough = FALSE, crs0 = fm_crs(x))
# S3 method for fm_collect
fm_transform(x, crs = fm_crs(x), ..., passthrough = FALSE, crs0 = NULL)
# S3 method for fm_lattice_2d
fm_transform(x, crs = fm_crs(x), ..., passthrough = FALSE, crs0 = fm_crs(x))
# S3 method for fm_segm
fm_transform(x, crs = fm_crs(x), ..., passthrough = FALSE, crs0 = fm_crs(x))
# S3 method for fm_list
fm_transform(x, crs, ...)

Value

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

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!

Examples

fm_transform(
  rbind(c(0, 0), c(0, 90), c(0, 91)),
  crs = fm_crs("sphere"),
  crs0 = fm_crs("longlat_norm")
)
