fclust (version 1.0.1)

Hraw: Raw prototypes

Description

Produces prototypes using the original units of measurement of X (useful if the clustering algorithm is run using standardized data).

Usage

Hraw (X, H)

Arguments

X

Matrix or data.frame

H

Prototype matrix

Value

• Hraw
  Prototypes matrix using the original units of measurement of X

Examples

## example n.1 (k-means case)
data(unemployment)
unempFKM=FKM(unemployment,k=3,stand=1)
unempFKM$H
unempFKM$Hraw=Hraw(unempFKM$X,unempFKM$H)
## example n.2  (k-medoids case)
data(unemployment)
## It may take more than a few seconds
unempFKM.med=FKM.med(unemployment,k=3,RS=10,stand=1)
## in the fuzzy k-medoids algorithm, one can equivalently use
unempFKM.med$Hraw1=Hraw(unempFKM.med$X,unempFKM.med$H)
unempFKM.med$Hraw2=unempFKM.med$X[unempFKM.med$medoid,]
