Quadratik

=========================

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.

=========================

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).

=========================

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

=========================

NEW FEATURES

* Add GitHub links to the DESCRIPTION file
* Add unit tests
* Add CONTRIBUTING.md
* Add srr standards for the categories: General, Clustering and Probability Distributions
* Add methods for the clustering object `pkbc`: `show()`, `summary()`, `estract_stats()`, `plot()` and `predict()`
* 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()`
* Modify indentation and assignments (using '<-') following `goodpractice` standards
* 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
* Update References in the DESCRIPTION file

=========================

NEW FEATURES

* released to CRAN
