⚠️There's a newer version (0.2.2.0) of this package.Take me there.

amt (animal movement tools)

The aim of amt is to make handling and analyzing animal telemetry data easier by providing functions that simplify common tasks, such as data filtering, calculation of path characteristics and home ranges, and the preparing data for more complex analyses (e.g., step selection functions and alike).
