QuadratiK 1.1.3 (2025-02-04)

NEW FEATURES

• the function rpkb() returns directly the generated data set and not a list.
  • change repository name from QuadratiK-package to QuadratiK.

MINOR IMPROVEMENTS

• packages ggplot2 and foreach not called as full packages but using importFrom.
  • nClust argument of pkbc function has no default value.
  • usage of standardGeneric (see https://adv-r.hadley.nz/s4.html#s4-generics).

BUG FIXES

• goodpractice suggestions.
  • specify that rho in pk.test() cannot be equal 1.
  • styling and spelling errors.

DOCUMENTATION FIXES

• Uniform notation: d is dimension in Eucldean space with spherical data lying on the (d-1)-dimensional sphere
  • Specify dimension of input matrix x in clustering functions.
  • Improve explanation of Average Silhouette Width.
  • Better explanation of motivation for L2 normalization in the wireless data set application.

QuadratiK 1.1.2 (2024-10-29)

NEW FEATURES

• Added NEWS.md file.

  • More detailed information in the README file and documentation (the methods are more usable and clearer for a broader audience).

MINOR IMPROVEMENTS

• Added badges for rOpenSci review status, test coverage, R CMD CHECK, CRAN downloads.
  • Addition of test codes with testthat package.
  • In particular, testing that random sampling from the PKBD and the wrapped Cauchy distribution is equivalent.

BUG FIXES

• scatter-plots related to the clustering algorithm results.
  • computation of evaluation measures (pkdc_validation function) when the true labels are not provided.

DOCUMENTATION FIXES

• The help documentation for the methods defined for the classes in the package can be accessed directly (addition of roxygen tag name and aliases).

QuadratiK 1.1.1 (2024-06-05)

NEW FEATURES

• Improve computation of variance for k-sample test
  • Add breast_cancer and wine data sets

MINOR IMPROVEMENTS

• print() and summary() methods of the kb.test object for the two and k-sample tests

BUG FIXES

• Computation of test statistics for normality test

DOCUMENTATION FIXES

• Correction of typos

  • Add vignette generate_rpkb.Rmd
  • Add CODE_OF_CONDUCT.md
  • Create the GitHub page using pkgdown
  • Add V-statistic for Normality test, with corresponding Critical Value and Degrees of Freedom with the function DOF_norm()
  • Update kb.test S4 class slots, kb.test() function, unit-test codes, summary() and print() method for including the V-statistic
  • Add Trace statistic for two and k-sample tests
  • Add computation of the Variance for two and k-sample tests

MINOR IMPROVEMENTS

• Addition of GitHub workflows for R-CMD-check, test-coverage and pkgcheck
  • Update codes to check arguments of function pk.test()
  • Update codes to check arguments of function kb.test() and select_h()

  • Update references in README.md file

BUG FIXES

• Add codemeta.json to .Rbuildignore

  • Add CONTRIBUTING.md to .Rbuildignore

  • Fix warning from internal function compare_qq()

  • Add doc folder to .gitignore

  • Modify returned test statistics multiplying them by the sample size

  • Remove "Nonparam" centering option for the Normality test

  • Critical value of the V-statistic divided by the variance in the function pk.test()

DEPRECATED AND DEFUNCT

• summary_stat() and validation() substituted by estract_stats() and pkbc_validation()

DOCUMENTATION FIXES

• C++ functions are set as internal functions
  • Correction of typos
  • Remove Date from DESCRIPTION
