Package repository has changed to now https://github.com/AustralianAntarcticDivision/traipse, for issues and information.
traipse now depends on CRAN package geographiclib.
Entirely removed geosphere dependency.
Now using geographiclib, have equivalence for bearings, angles, and turns. Better accuracy now for ‘track_intermediate()’ on exact ellipsoidal calculations.
Fixed: track_angle and track_turn now return all-NA for fewer than 3 input points.
New function ‘track_grid()’ to compute cell index for points for a grid.
Fixed test failing as newer R allows raw numeric input to date-time.
New function track_query() similar to
track_intermediate() but for arbitrary points in time.
In-development.
New function track_intermediate() to perform
interpolation along a great circle between input locations. The
interpolation step may be set by distance or
duration and date-time is interpolated if
included.
Metres, seconds, degrees, everywhere.
Fixed Value documentation for various functions, thanks to CRAN feedback.
New functions track_time,
track_speed,track_distance_to() and
track_bearing_to().
Added basic functions track_distance,
track_angle, track_turn, and
track_bearing.
