Calculates entropy based on heights, 2D, or 3D positions of points.
Usage
entropy(data, ...)
Value
A value for entropy.
Arguments
data
Digital elevation model of class RasterLayer, a triangular mesh of class mesh3d, or a pointcloud of class data.frame.
...
Additional arguments depending on the data type.
Details
If data is a 3D pointcloud or 3D mesh, entropy_3d() function will be applied;
if data is a 2D pointcloud,entropy_2d() will be applied; and if data is a RasterLayer, entropy_1d() will be applied after conversion to a vector.
See the documentation of those functions for details on the necessary arguments.
