Get the distance and time range of each trip in a trajectory object

This function extracts the time and distance ranges stored in a trajectory object and formats them into a dataframe. The dataframe can be filtered to a desired set of trip_id_performeds.

Usage

get_trip_extremes(trajectory, filter_trips = NULL)

Arguments

trajectory: A trajectory object.
filter_trips: Optional. A vector of trip_id_performeds to filter the dataframe to. At least one must of filter_trips must be present in trajectory. Default is NULL, where all trip_id_performeds in trajectory are returned.

Value

A dataframe with the columns trip_id_performed, min_time, max_time, min_dist, and max_dist.

Examples

# Get input data
lineE_traj <- new_transittraj_data("get_trajectory_fun")

# Run function
lineE_extremes <- get_trip_extremes(lineE_traj)
print(lineE_extremes)
