FHD                     Foliage Height Diversity
GC                      Gini coefficient of foliage structural
                        diversity
GS                      Gini-Simpson index of foliage structural
                        diversity
LAHV                    Leaf Area Height Volume metric
k.coefficient           Calculate k coefficient provided a known real
                        LAI and the calculated LAI
lad.profile             This function calculate the lad profile from
                        the input lad.voxels
lad.voxels              Creates a data frame of the 3D voxels
                        information (xyz) with Leaf Area Density values
                        from las file
lai                     calculates the lead area index (LAI)
lai.raster              Produce a raster map of LAI. The resolution of
                        the raster depends of grain.size choosed on
                        lad.voxel() funtion.
lidar_example.laz       lidar_example.laz included raw data
pointsByZSlice          Count number of points in each Z slice
