## S4 method for signature 'RasterLayer'
setValues(x, values, ...)

## S4 method for signature 'RasterBrick'
setValues(x, values, layer=-1, ...)

## S4 method for signature 'RasterStack'
setValues(x, values, layer=-1, ...)

## S4 method for signature 'RasterLayerSparse'
setValues(x, values, index=NULL, ...)

values(x) <- value

Arguments

x

A Raster*

values

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

value

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

layer

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

index

Cell numbers corresponding to the values

...

Additional arguments (none implemented)

Value

a Raster* object

Note

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 setValues takes care of.
