A space-time raster dataset is a collection of raster layers indexed by time, or in other words, a time series of raster maps. The raster package defines the classes RasterStack and RasterBrick to build multilayer rasters. The index of the collection can be set with the function setZ (which is not restricted to time indexes). The rasterVis packages provide several methods to display space-time rasters.
