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

Description

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

Usage

# S4 method for 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 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 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 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.
