assert_that_raster_covers_las_point_cloud
                        Assert that the extent of a raster covers that
                        of a LAS point cloud
calculate_centroids_flexible
                        Searches modes with the AMS3D algorithm for a
                        lidar point cloud of a forest
extract_coordinate_values
                        Extract coordinate data from a data.frame-like
                        object

                        height for AMS3D
li_diameter_raster,LAS-method
                        Calculate a raster of crown diameter to tree
                        height using watershed segmentation
match_any               Find all exact matches with at least one of the
                        provided patterns
remove_small_trees      Remove small clusters from segmented point
                        cloud
segment_tree_crowns     Segment Tree Crowns in a 3D Point Cloud
segment_tree_crowns_core
                        Calls the C++ back-end and the DBSCAN algorithm
                        to perform the segmentation
validate_scale_n_offset_are_consistent
                        Asserts that all files referenced by a
                        LAScatalog have the same scale and offset
                        values.
validate_write_crown_id_also_to_file_for_LAScatalogs
                        Ensures that crown IDs are written to output
                        files of the LAScatalog
