argos.sigma

Assign numeric values for Argos "class" by matching the levels available to
given numbers. An adjustment is made to allow sigma to be specified in
kilometres, and the values returned are the approximate values for longlat
degrees. It is assumed that the levels are part of an "ordered" factor from
least precise to most precise.

manip

Access and manipulate spatial tracking data, with straightforward
coercion from and to other formats. Filter for speed and create time spent
maps from tracking data. There are coercion methods to convert between 'trip'
and 'ltraj' from 'adehabitatLT', and between 'trip' and 'psp' and 'ppp' from
'spatstat'. Trip objects can be created from raw or grouped data frames, and
from types in the 'sp', sf', 'amt', 'trackeR', 'mousetrap', and other packages,
