Distance towards the next coordinate in the tracks.
t_distance( tracks, bind = TRUE, drop = TRUE, cname = "distances_in_m", t_id = "id" )

cname |

t_id |
character or numeric. Column name in |
For the last coordinate within a track the function returns empty
because there is no distance towards a following coordinate possible. Using 0 instead of NA may be an unwanted bias within the data.
The distance between the first and the second point is stored with the second point. This is done for higher compatibility with the gap functions.
