ecotraj 1.0.0

• Trajectory data structures have been introduced.
• New functions for cyclical trajectory analysis (Djeghri et al, in prep.).
• New ETA metrics trajectoryVariability() and trajectorySpeeds().
• Permutational test added for trajectoryDirectionality().
• New function trajectoryMetrics() for evaluation of multiple metrics.
• New function trajectoryWindowMetrics() for metrics evaluated over moving windows.
• New function trajectoryShifts() to compare trajectories that are similar in shape but differ in speed.
• New dissimilarity metric for trajectories, taking into account differences in time.

ecotraj 0.2.1

• Update of function ‘centerTrajectories’ to add flexibility in trajectory centroid definition.
• New vignette to illustrate centering.
• Improvement of trajectoryProjection() to return relative position within selected segments, also when orthogonal projection does not exist.

ecotraj 0.2.0

• New function ‘smoothTrajectories’ added.
• Update of vignette ‘Introduction to to Ecological Trajectory Analysis (ETA)’.
• Correction of squared distances to centroid (GitHub issue #3).
• EQA between individual states and dynamic envelopes (experimental).

These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
