gtfstools v1.1.0

New features

• New function convert_time_to_seconds().
• New function filter_by_agency_id().
• New function filter_by_service_id().
• New function filter_by_time_of_day().
• New function filter_by_weekday().
• New function frequencies_to_stop_times().
• New function get_children_stops().
• New function get_stop_times_patterns().
• New function get_trip_length().
• New parameter to merge_gtfs(): prefix. The warnings parameter
  was flagged as deprecated.
• Functions get_parent_station() and get_children_stops now accept
  stop_id = NULL to analyze all stop_ids in the stops table.

Bug fixes

• Fixed a bug in which get_trip_segment_duration() would list wrong
  segment numbers, not necessarily starting from 1. Now segment numbers
  always range from 1 to N, where N is the total number of segments that
  compose each trip.
• Fixed a bug in filter_by_{route,service,shape,trip}_id() that
  resulted in the agency table not getting filtered when the specified
  id was character(0).

Notes

• Performance improvements to get_trip_geometry(),
  get_trip_duration(), get_trip_segment_duration() and
  convert_shapes_to_sf().
• Stopped ordering points by shape_pt_sequence/stop_sequence in
  get_trip_geometry() and convert_shapes_to_sf(), since the GTFS
  reference says that the stop_times and shapes tables must be
  ordered by point/stop sequence anyway.
• Removed {lwgeom} from dependencies (Suggests), now that it's not
  required to run get_trip_speed() and set_trip_speed() anymore.
• Removed the warnings parameter from read_gtfs() and write_gtfs()
  and the optional and extra parameters from write_gtfs(), flagged
  as deprecated on gtfstools v1.0.0.
• Updated filtering vignette to demonstrate new functions.
