Levelplot is a command in the `lattice` graphics package for `r` that displays three dimensional data using a false-color gradient.

Levelplot is a command in the lattice graphics package for r that displays three dimensional data using a false-color gradient. The x and y data are plotted used to indicate position on the x- and y- axis. The z data is used to determine the color of that position. Note that the x and y coordinates are assumed to define a regular grid.
