FuzzyNumber class' fnAlphaLevels private field has been replaced by three attributes alphaLevels, infimums and supremums which corresponds with the first, second third column of a fuzzy number respectively.
FuzzyNumber class' getFnAlphaLevels public method has been replaced by three methods getAlphaLevels, getInfimums and getSupremums which returns the corresponding class' attributes.
FuzzyNumber class' checkValidity private method has a new parameter fnLevels that corresponds with the numbers specified and given by the current constructor (initialize). That parameter is used as the previous attribute fnAlphaLevels in the body method.
FuzzyNumber class' checkValidity private method does not generate a new object of class FuzzyNumber if it is not valid, in that case an error is thrown.
FuzzyNumber and TrapezoidalFuzzyNumber classes' valid private field has been removed as no invalid objects can be generated. Therefore, the public method is_valid has been removed too.
FuzzyNumber class' current constructor (initialize) now sets all its attributes if the checkValidity method does not thrown an error.
The public field numbers at FuzzyNumberList and TrapezoidalFuzzyNumberList classes has become a private field.
The public method checking at TrapezoidalFuzzyNumberList and StatList classes has been removed. That method at FuzzyNumberList class has become a private method. In that last class, its parameter has changed from verbose to numbers, which corresponds with the numbers specified and given by the current constructor (initialize). method only checks if the alpha-levels of the numbers are equal, apart from setting the class' attributes.
FuzzyNumberList class' current constructor (initialize) instead of setting the class' attributes, it calls the private checking method.
TrapezoidalFuzzyNumber class' checkValidity private method has been removed. Its functionality has been moved to the current constructor (initialize). In case of trying to generate a new invalid object of class TrapezoidalFuzzyNumber, an error is thrown.
The programming of classes FuzzyNumberList, TrapezoidalFuzzyNumberList, Simulation and Utils have changed in accordance with the current numbers private field and the new getLength method.
Titles and descriptions of the FuzzyNumber, TrapezoidalFuzzyNumber, FuzzyNumberList and TrapezoidalFuzzyNumberList has been updated and modified in accordance with the validity of the numbers.
The documentation of the public fields and methods have been updated or modified in accordance with the changes made.
All tests and the required examples have been updated or modified in accordance with the previous changes.
The import from testhat in the FuzzyStatTraEOO-package file was removed.
testhat in the DESCRIPTION file was moved from Imports to Suggests.
DESCRIPTION file was updated as follows:
Version field was updated with value 1.0.Date field was updated with the starting date of the new version.Suggests field.FuzzyStatTraEOO-package file was updated as follows:
Version field was updated with value 1.0.Date field was updated with the starting date of the new version.The package can only work with valid FuzzyNumber and TrapezoidalFuzzyNumber object. Therefore, the FuzzyNumberList and TrapezoidalFuzzyNumberList object can only contain valid numbers.
FuzzyNumber, TrapezoidalFuzzyNumber, FuzzNumberList and TrapezoidalFuzzyNumberList classes have a new method plot in order to show it/them in a graph. The color used can be specified. Therefore, that method has been added to the class StatList too.
FuzzNumberList, TrapezoidalFuzzyNumberList and StatList classes has a new public method getLength to counteract the visibility usage of the numbers attribute. It provides a counter of how many numbers the classes have.
Tests for code lines were developed through the testthat and vdiffr (used specifically for plot methods) packages. These tests provide a 100% coverage as it was calculated by package_coverage() function from covr package.
nl of medianWabl, media1Norm and transfTra methods of the class TrapezoidalFuzzyNumberList was specified and restricted to be greater than 0 but it must be greater or equal to two.Initial release of the FuzzyStatTraEOO package on the Comprehensive R Archive Network (CRAN).
