fdasrvf 2.0.2.900

fdasrvf 2.0.2

• added dynamic grid to DP method (#25)
• update outputs to curve functions (#26)
• extend exp_map to n-d curves (#27)
• bugfixes

fdasrvf 2.0.1

• Added functionalities to kmeans_align() (#24). Specifically:

  • it gains the argument use_verbose which allows the user to suppress information displayed in the console;
  • it includes a numeric vector storing the distances to corresponding center for each curve in the output;
  • it is now possible to use the medoid as centroid type as an alternative to the mean; the medoid is the most central curve among the existing curves.

• Further small improvements, documentation updates and improved code coverage (#23).

fdasrvf 2.0.0

• Added multivariate kmeans (#18);
• Added additional penalties to warping and additional outputs exposed to bootTB() (#19);
• Switch from travis appveyor to GHA for CI and code coverage monitoring (#20);
• Bugfixes and documentation updates.
