Arguments

x	Raster* layer. The layer that zonal statistics should be calculated from.
z	Raster* layer. A rasterized version of the zonal layer.
stat	character. Name of statistic used to calculate a value across each polygon in z. ex. "mean", "sum".
digits	numeric. Number of significant digits in zonal statistic output.
