Rename layers/attributes

rename() changes the names of individual layers/attributes using new_name = old_name syntax; rename_with() renames layers/attributes using a function.

Usage

# S3 method for SpatRaster
rename(.data, ...)

# S3 method for SpatRaster
rename_with(.data, .fn, .cols = everything(), ...)

# S3 method for SpatVector
rename(.data, ...)

# S3 method for SpatVector
rename_with(.data, .fn, .cols = everything(), ...)

Arguments

.data

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

...

Depending on the function:

• For rename.Spat*(): <tidy-select>. Use new_name = old_name to rename selected variables.

• For rename_with(): additional arguments passed onto .fn.

.fn

A function used to transform the selected .cols. Should return a character vector the same length as the input.

.cols

<tidy-select> Columns to rename; defaults to all columns.

Value

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

terra equivalent

names(Spat*) <- c("a", "b", "c")

Methods

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

SpatRaster

Rename layers of a SpatRaster.

SpatVector

The result is a SpatVector with the renamed attributes on the function call.
