largest_eafdiff: Identify largest EAF differences

Description

Given a list of datasets, return the indexes of the pair with the largest EAF differences according to the method proposed by DiaLop2020ejor;textualeaf.

Usage

largest_eafdiff(data, maximise = FALSE, intervals = 5, reference, ideal = NULL)

Arguments

data

(list(1)) A list of matrices with at least 3 columns

maximise

(logical() | logical(1)) Whether the objectives must be maximised instead of minimised. Either a single logical value that applies to all objectives or a vector of logical values, with one value per objective.

intervals

(integer(1)) The absolute range of the differences \([0, 1]\) is partitioned into the number of intervals provided.

reference

(numeric()) Reference point as a vector of numerical values.

ideal

(numeric()) Ideal point as a vector of numerical values.

Value

(list()) A list with two components best_pair and best_value.
