Description

Determine stop locations in trajectory data via TDBC

Usage

tdbc(trajectory)

Arguments

trajectory	A simple features collection representing a single trajectory.
eps	distance threshold for defining clusters
minpts	minimum number of points in a cluster

Details

Examples

trajectory <- trajectories %>%  filter(id == "131") %>%
  mutate(day = day(localtime)) %>% filter(day == 16)
