Fuzzy-logic analysis of dendrogram clusters selected by the researcher

Share:

Description

This function provides fuzzy-logic descriptions and inter-relationships for all clusters in the dendrogram on which the analyst wishes to put the focus.

Usage

1
fuzzy.Clusters(macoquires, grupos)

Arguments

macoquires

object resulting from function macoqui

grupos

dendrogram clusters -identified by the analyst- on which the analysis is focused

Details

Before applying fuzzy.Clusters, macoqui must be run, and outputs must be stored as object 'macoquires'.

grupos <- c(n, b, ...), where:

n dendrogram-node number (as in the dendrogram plot) b node-branch corresponding to the cluster (1 if left, 2 if right) ... idem for all clusters to be analized

Value

This function returns a list of 9 elements, some of which are shown in the console:

ngrupos

the input number of analysed groups

grupos

the input groups object

desGrupos

a description of the input groups, including their node and branch

elementosGrupos1
elementosGrupos2
ldifusaGrupos

parameters to compute cluster fuzzy entropy, fuzzy union of clusters, and fuzzy intersection between clusters

mcardinales

cardinals of fuzzy unions between clusters (top-right semi-matrix), and of fuzzy intersections between clusters (bottom-left semi-matrix)

mentropia

cluster fuzzy parameters (cardinal, entropy, height) and number of species in the cluster; fuzzy inclusion of the cluster in other clusters; fuzzy overlap between clusters

datos

the input species dataset
