Changes in version 1.3.1 (2024-05-23)                  

Improvements

  - plot_archs() remove option for creating polygon in 3D
  - plot.archetypal() remove option for creating polygon in 3D

New S3 classes

  - print.archetypal() It prints the output of archetypal()
  - summary.archetypal() It gives a summary for the output of
    archetypal()
  - plot.archetypal() It makes a plot of the archetypes creating after
    using archetypal()
  - plot.kappa_tools() It makes a plot of the results created after
    using kappa_tools()
  - plot.study_AAconvergence() It makes a plot of the results created
    after using study_AAconvergence()

New functions

  - plot_archs() plots a matrix or data frame of archetypes

New functions

  - find_pcha_optimal_parameters() finds the optimal parameters to be
    used for PCHA algorithm.
  - find_closer_points() finds the data points that are closer to the
    archetypes during all iterations of algorithm PCHA.
  - study_AAconvergence() studies the convergence of Archetypal Analysis
    when using algorithm PCHA.
  - grouped_resample() performs simple or Dirichlet resampling.

    Northern Hemisphere 1969-

2013. 
  - gallupGPS6 the Gallup Global Preferences Study processed data set of
    six variables.

Minor changes

  - find_outmost_projected_convexhull_points changes its n argument to
    npr and has new arguments rseed, doparallel, nworkers and
    uniquerows.
  - check_Bmatrix changes its print.details argument to verbose.
  - find_furthestsum_points changes its nworkers = 10 argument to
    nworkers = NULL and has new argument doparallel.
