moveMerger {stopdetection}

Move Merger

Description

Handles move/track events that do not meet specific thresholds to be considered. This is based on the researcher-decided total number of allowable locations that the discarded track can consist of, as well as a maximum total time length that may elapse. Tracks can be merged into the preceding stop or excluded. Future versions of this should consider assigning to the closest stop for small_track_action = merge.

Usage

moveMerger(
  events,
  small_track_action = "merge",
  max_locs = 1,
  max_time = 600,
  max_dist = 100
)
