archetypal 1.3.1 (2024-05-19) - minor update

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

archetypal 1.2.1 (2021-11-19)

New functions

• kappa_tools() computes a set of proxies for the dimensionality

archetypal 1.1.1 (2020-10-09)

• fix a bug for OS r-patched-solaris-x86

archetypal 1.1.0 (2020-01-27) - major update

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.
• dirichlet_sample() performs Dirichlet sampling.

New data sets

• Absolute Temperature the Global Absolute Temperature data set for Northern Hemisphere 1969-

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

• wd25 a 2D data set created by 5 points for demonstration purposes.

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.
• align_archetypes_from_list has a new argument verbose.

These binaries (installable software) and packages are in development.
