### Examples

    data(meuse.riv)
    plot(meuse.riv, type = "l", asp = 1)
    data(meuse.grid)
    coordinates(meuse.grid) = c("x", "y")
    gridded(meuse.grid) = TRUE
    image(meuse.grid, "dist", add = TRUE)
    data(meuse)
    coordinates(meuse) = c("x", "y")
    meuse.sr = SpatialPolygons(list(Polygons(list(Polygon(meuse.riv)),"meuse.riv")))
    spplot(meuse.grid, col.regions=bpy.colors(), main = "meuse.grid",
      sp.layout=list(
            list("sp.polygon", meuse.sr),
            list("sp.points", meuse, pch="+", col="black")
      )
    )
    spplot(meuse, "zinc", col.regions=bpy.colors(),  main = "zinc, ppm",
      cuts = c(100,200,400,700,1200,2000), key.space = "right",
