raster (version 1.8-3)

setValues: Set values of a Raster object

Description

You can use the setValues function to assign values to a RasterLayer or RasterBrick object. While you can access the 'values' slot of the objects directly, you would do that at your own peril because when setting values, multiple slots need to be changed; which is what these functions do.

Usage

setValues(x, values, layer) 
values(x) <- value

Arguments

x

A RasterLayer or RasterBrick object

values

Cell values to associate with the RasterLayer object. There should be values for all cells

value

Cell values to associate with the RasterLayer object. There should be values for all cells

layer

Layer number (only relevant for RasterBrick objects). If missing, the values of all layers is set

Value

• a Raster* object

r[] <- vals
