CPart {FKBL}R Documentation

Creates a fuzzy partition

Description

This is the implementation in R of a fuzzy partition, described in, chapter 1, pages 005-009 at Ishibuchi et al. . It has a sister function, with different parameter, but with the same objective. It provides a wrapper to create the appropriate list with the appropriate codes. A partition is defined by a set of values which mark the limits and top point of every triangular division. The divisions are in a chain, the left and right limit of a division, are the top points of its neighbors. And in the same way, the top point of a given partition is the limit of its neighbors. Graphically this is a succession of mixed triangles, where the projection of a height of a given triangle marks the point where two triangles join.

Usage

 CPart(elem, min, max)

Arguments

Takes the number of elements and the minimum and maximum value of the partition.

elem The number of elements of the partition.
min The minimum value of the partition.
max The maximum value of the partition.

Value

Returns a list, the first three elements (numElem, numMin and numMax) are the arguments given to the function. The fourth one, is the actual partition.
list(numMin=x1, numMax=x2, part=x3, numElem=x5)

Examples

 CPart(3,0.0,1.0) # 0.0 0.5 1.0
