Change layer/attribute order

Use relocate() to change layer/attribute positions, using the same syntax as select.Spat to make it easy to move blocks of layers/attributes at once.

Usage

# S3 method for class 'SpatRaster'
relocate(.data, ..., .before = NULL, .after = NULL)

# S3 method for class 'SpatVector'
relocate(.data, ..., .before = NULL, .after = NULL)

Arguments

.data

A SpatRaster created with terra::rast() or a SpatVector created with terra::vect().

...

<tidy-select> layers/attributes to move.

.before, .after

<tidy-select> Destination of layers/attributes selected by .... Supplying neither will move layers/attributes to the left-hand side; specifying both is an error.

Value

A Spat* object of the same class than .data. See Methods.

terra equivalent

terra::subset(data, c("name_layer", "name_other_layer"))

Methods

Implementation of the generic dplyr::relocate() function.

SpatRaster

Relocate layers of a SpatRaster.

SpatVector

The result is a SpatVector with the attributes on a different order.
