Replace layers of a RasterArray or SpatialArray object
Single bracket '[' refers to indices and names within the \codeRasterArray or SpatialArray. Use double brackets to replace layers based on their names (in the stack).
RasterLayers and RasterArray entries can be used to replace values in RasterArrays. Spatial* objects and SpatialArrays can be used with SpatialArrays.
