  "Description": "Access and manipulate spatial tracking data, with\nstraightforward coercion from and to other formats. Filter for\nspeed and create time spent maps from tracking data. There are\ncoercion methods to convert between 'trip' and 'ltraj' from\n'adehabitatLT', and between 'trip' and 'psp' and 'ppp' from\n'spatstat'. Trip objects can be created from raw or grouped\ndata frames, and from types in the 'sp', sf', 'amt', 'trackeR',\n'mousetrap', and other packages, Sumner, MD (2011)\n<https://figshare.utas.edu.au/articles/thesis/The_tag_location_problem/23209538>.",
