 Plotting objects inheriting from this class or related classes (e.g. `SpatialGridDataFrame`) is straightforward using the `spplot` methods, as described in [wiki:../Trellis the previous example], but it is not directly usable as input for other plotting methods in R.
 Next, we present some typical plotting functions and how to extract the spatial coordinates in a suitable format for plotting.
+
+The total precipitation field is calculated as the total accumulated precipitation during the selected period for each model grid cell:
+
+{{{
+tp <- colSums(monsoon$MemberData$Member_16) 
+}}}
+
+And this is the classical way of displaying the data using the `spplot` method:
+
+{{{
+sgdf <- SpatialGridDataFrame(monsoon$LonLatCoords, as.data.frame(tp))
+data(world_map)
+wl <- as(world_map, "SpatialLines")
+wlines <- list("sp.lines", wl)
+spplot(sgdf, scales = list(draw = TRUE), sp.layout = list(wlines), col.regions = rev(topo.colors(41)))
+}}}
+

+
+It is also straightforward to represent the precipitation using contour lines:
+
+{{{
+spplot(sgdf, scales = list(draw = TRUE), contour = TRUE, col = "red", col.regions = rev(topo.colors(41)))
+}}}
