Track collective events
trackColl(obj, eps = 1, minClSz = 1L, nPrev = 1L, epsPrev = NULL, deb = FALSE)
# S3 method for arcosTS
trackColl(obj, eps = 1, minClSz = 1L, nPrev = 1L, epsPrev = NULL, deb = FALSE)an arcosTS object.
a numeric, sets the search radius for spatial clustering with dbscan; default 1.
an integer, minimum cluster size for dbscan; default 1L.
an integer, number of previous frames to link; default 1L.
a float with the search radius for linking clusters between frames, default NULL means that epsPrev = eps.
boolean, additional debug output; default FALSE.
an arcosTS object
Wrapper for the trackCollEvents function.
