as.PiecewiseLinearFuzzyNumber: Converts an Object to a Piecewise Linear Fuzzy Number

In gagolews/FuzzyNumbers: Tools to Deal with Fuzzy Numbers

Description

This method is only for exact conversion. For other cases (e.g. general FNs), use piecewiseLinearApproximation.

Usage

## S4 method for signature 'TrapezoidalFuzzyNumber'
as.PiecewiseLinearFuzzyNumber(object, knot.n=0,
   knot.alpha=seq(0, 1, length.out=knot.n+2)[-c(1,knot.n+2)])

## S4 method for signature 'numeric'
as.PiecewiseLinearFuzzyNumber(object, knot.n=0,
   knot.alpha=seq(0, 1, length.out=knot.n+2)[-c(1,knot.n+2)])

## S4 method for signature 'FuzzyNumber'
as.PiecewiseLinearFuzzyNumber(object, knot.n=0,
   knot.alpha=seq(0, 1, length.out=knot.n+2)[-c(1,knot.n+2)])

## S4 method for signature 'PiecewiseLinearFuzzyNumber'
as.PiecewiseLinearFuzzyNumber(object, knot.n=0,
   knot.alpha=seq(0, 1, length.out=knot.n+2)[-c(1,knot.n+2)])

Arguments

object	a fuzzy number or a single numeric value (crisp number) or vector of length two (interval)
knot.n	the number of knots
knot.alpha	knot.n alpha-cut values at knots, defaults to uniformly distributed knots

Value

Returns an object of class PiecewiseLinearFuzzyNumber.
