Is it possible in R to create a color key like the one below? (this one comes from the software Grid Analysis and Display System - Grads).
There are two features that I can't reproduce in R:

I am trying to use levelplot to plot a simple Digital Elevation Model (DEM).
Here is my code:
r1 = raster("ned10dem.tif")
e = extent(460000,480000,4555000,4567500)
rr1 = crop(r1,e)
