Raster* object (or a SpatialPixels* or SpatialGrid* object)
cells
vector of cell numbers
values
Logical. If TRUE, the new RasterLayer has cell values that correspond to the cell numbers of x

Cell numbers start at 1 in the upper left corner, and increase from left to right, and then from top to bottom. The last cell number equals the number of cells of the Raster* object.
