SAFD (version 2.1)

decomposer: Decomposer

Description

Given a dataframe X the function first calls checking in order to test if X is in the desired format. If yes, the dataframe X (polygonal fuzzy number) is expressed as a dataframe with (nrow(X)+1) rows as described in the paper [1] below, if no, NULL is returned. The main aim of decomposer is to provide the simulator-function called generator with the correct input.

Usage

decomposer(X)

Arguments

X

...dataframe, if checking(X)=1 the decomposed version of X is returned.

Value

In case checking(X)=1 decomposer returns a dataframe with (nrow(X+1))-rows (see [1]), otherwise NA is returned.
