Package index • clusterTrack

Main clustering function

High-level track clustering and post-processing.

cluster_track(): Cluster a movement track into spatiotemporal clusters
aggregate_ctdf(): Aggregate (merge) adjacent clusters by spatial proximity
summary(<ctdf>): Summarise a ctdf by cluster

Core data format

Coercion and helpers around the ctdf format.

as_ctdf(): Coerce an object to clusterTrack data format
as_ctdf(<data.frame>): Coerce an object to clusterTrack data format
as_ctdf_track(): Convert a ctdf track to movement step segments as LINESTRINGs

Pipeline steps

Lower-level steps used by cluster_track().

slice_ctdf(): Slice a CTDF into putative clusters using temporal continuity and spatial clustering
spatial_repair(): Repair spatially overlapping adjacent putative clusters
local_cluster_ctdf(): Local clustering using DTSCAN
temporal_repair(): Repair temporally overlapping putative clusters
tail_repair(): Repair putative clusters by trimming track tails

Spatial clustering backends

DTSCAN and time-aware DBSCAN.

sf_dtscan(): DTSCAN: Delaunay Triangulation-Based Spatial Clustering.
tdbscan(): tdbscan
