In ClustBlock: Clustering of Datasets

Change format of CATA datasets to perform the package functions

Description

CATATIS and CLUSCATA operate on data where the blocks of variables are merged horizontally. If you have a vertical format, you can use this function to change the format. The first column must contain the sessions, the second the subjects, the third the products and the others the attributes. If you don't have sessions, then the first column must contain the subjects and the second the products. Unlike change_cata_format function, you can enter data with sessions and/or mixed data in terms of products/subjects. However, you have to set columns to indicate this beforehand.

Usage

change_cata_format2(Data, nprod, nattr, nsub, nsess)

Arguments

Data	data frame or matrix. Correspond to your data
nprod	integer. Number of products
nattr	integer. Number of attributes
nsub	integer. Number of subjects.
nsess	integer. Number of sessions

Value

The arranged data for CATATIS and CLUSCATA function and the subjects names in the correct order.

Examples

#Vertical format with sessions
data("fish")
chang=change_cata_format2(fish, nprod= 6, nattr= 27, nsub = 12, nsess= 3)
res.cat2=catatis(Data= chang$Datafinal, nblo = 12, NameBlocks =  chang$NameSub)

#Vertical format without sessions
Data=fish[1:66,2:30]
chang2=change_cata_format2(Data, nprod= 6, nattr= 27, nsub = 11, nsess= 1)
res.cat3=catatis(Data= chang2$Datafinal, nblo = 11, NameBlocks =  chang2$NameSub)
res.clu3=cluscata(Data= chang2$Datafinal, nblo = 11, NameBlocks =  chang2$NameSub)
