Hello,

In rasterVis there is a method to produce histograms with a formula and a
Raster* object. The last example of the help page of rasterVis::histogram
illustrates this usage.
In the formula, you can include names of layers, "x" and "y" (coordinates),
and "dirXY" if you supply this argument in histogram.

Best,

Oscar.
