ecotraj 1.1.0
- New functions is.metric() and is.synchronous().
- Update of function trajectoryInternalVariation() (former
trajectoryVariability()).
- New function dynamicVariation().
- New function variationDecomposition() for synchronous
trajectories.
- New function interpolateTrajectories() for interpolation to given
times.
- Function trajectoryConvergence() modified to allow a global
convergence test (type = “multiple”).
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).
