TrapezoidalFuzzyNumber {FuzzyStatTraEOO}R Documentation

R6 Class representing a 'TrapezoidalFuzzyNumber'.

Description

A 'TrapezoidalFuzzyNumber' is characterized by their four values inf0, inf1, sup1 and sup0. Its' values are checked in order to only provide a valid 'TrapezoidalFuzzyNumber'.

Methods

Public methods

Method new()

This method creates a valid 'TrapezoidalFuzzyNumber' object with all its attributes set.

Usage
TrapezoidalFuzzyNumber$new(inf0 = NA, inf1 = NA, sup1 = NA, sup0 = NA)
Arguments
inf0

is a real number that corresponds to the infimum of support of the trapezoidal fuzzy number.

inf1

is a real number that corresponds to the infimum of core of the trapezoidal fuzzy number

sup1

is a real number that corresponds to the supremum of core of the trapezoidal fuzzy numbers

sup0

is a real number that corresponds to the supremum of support of the trapezoidal fuzzy numbers

Details

See examples.

Returns

The TrapezoidalFuzzyNumber object created with all its attributes set if it is valid.

Examples
# Example 1:
TrapezoidalFuzzyNumber$new(1,2,3,4)

# Example 2:
TrapezoidalFuzzyNumber$new(-8,-6,-4,-2)

# Example 3:
TrapezoidalFuzzyNumber$new(-1,-1,2,3)

# Example 4:
TrapezoidalFuzzyNumber$new(1,2,3,3)

Method getInf0()

This method gives the inf0 attribute of the 'TrapezoidalFuzzyNumber'.

Usage

Returns

The inf0 attribute of the TrapezoidalFuzzyNumber object.

Examples
TrapezoidalFuzzyNumber$new(1,2,3,4)$getInf0()

Method getInf1()

This method gives the inf1 attribute of the 'TrapezoidalFuzzyNumber'.

Usage
TrapezoidalFuzzyNumber$getInf1()
Details

See examples.

Returns

The inf1 attribute of the TrapezoidalFuzzyNumber object.

Examples

Method getSup1()

This method gives the sup1 attribute of the 'TrapezoidalFuzzyNumber'.

Usage
TrapezoidalFuzzyNumber$getSup1()
Details

See examples.

Returns

The sup1 attribute of the TrapezoidalFuzzyNumber object.

Examples

Method getSup0()

This method gives the sup0 attribute of the 'TrapezoidalFuzzyNumber'.

Usage
TrapezoidalFuzzyNumber$getSup0()
Details

See examples.

Returns

The sup0 attribute of the TrapezoidalFuzzyNumber object.

Examples
TrapezoidalFuzzyNumber$new(1,2,3,4)$getSup0()

Method is_positive()

This method gives information whether the 'TrapezoidalFuzzyNumber' is positive regarding its attributes.

Usage
TrapezoidalFuzzyNumber$is_positive()
Details

See examples.

Returns

TRUE whether the TrapezoidalFuzzyNumber object has all its attributes greater than -1, otherwise FALSE.

Examples
# Example 1:
TrapezoidalFuzzyNumber$new(1,2,3,4)$is_positive()

# Example 2:
TrapezoidalFuzzyNumber$new(-8,-6,-4,-2)$is_positive()

Method plot()

This method shows in a graph the values of the corresponding 'TrapezoidalFuzzyNumber'.

Usage
TrapezoidalFuzzyNumber$plot(color = "grey")
Arguments
color

is the color of the lines representing the number to be shown in the graph. The default value is grey, other colors can be specified, the option palette() too.

Details

See examples.

Returns

a graph with the values of the corresponding 'TrapezoidalFuzzyNumber'.

Examples
# Example 1:
TrapezoidalFuzzyNumber$new(1,2,3,4)$plot()

# Example 2:
TrapezoidalFuzzyNumber$new(-8,-6,-4,-2)$plot("blue")

# Example 3:
TrapezoidalFuzzyNumber$new(0,0,0.5,3)$plot(palette())

# Example 4:
TrapezoidalFuzzyNumber$new(-8,-3.55,0,10)$plot(palette()[5])

Method clone()

The objects of this class are cloneable with this method.

Usage
TrapezoidalFuzzyNumber$clone(deep = FALSE)
Arguments
deep

Whether to make a deep clone.
