mousetrack (version 1.0.0)

mousetrack-package: Mouse-tracking measures from trajectory data.

Description

Extract from two-dimensional (x-y coordinates) of a trajectory several dependent measures, such as area under the curve, latency to start the movement, x-flips, etc. Mainly developed to analyze mouse-tracking data.
