decomposer: Decomposer
In SAFD: Statistical Analysis of Fuzzy Data

Description Usage Arguments Details Value Note Author(s) References See Also Examples

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.

1	decomposer(X)

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

See examples

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

In case you find (almost surely existing) bugs or have recommendations for improving the functions comments are welcome to the above mentioned mail addresses.
