ipeaGIT/gtfs2gps: v2.0-0

Major changes

• gtfs2gps() now creates two points for a stop when arrival and departure exist. Speed and travel time are now calculated considering both departure_ and arrival_time columns.
• The travel statistics in the output table (speed, dist, cumdist, cumtime) for a given point are now calculated in relation to the previous point. More details in the documentation of the gtfs2gps() function.
• Names of the output columns of gtfs2gps() were updated
• New function adjust_arrival_departure() to allow users set a minimum time for dis/embarking times at each stop.
• New function adjust_speed() to fix outlier speeds and replace missing speed values with a speed set by the user or the average speed of the system. The timestamp values are updated accordingly.
• Fixing several small errors in the output of gtfs2gps(), what breaks compatibility with previous versions of the gtfs2gps package.
