plot.cluscata_liking: Displays the CLUSCATA-liking graphs

In ClustBlock: Clustering of Datasets

Displays the CLUSCATA-liking graphs

Description

This function plots dendrogram, variation of the merging criterion, weights and CATATIS map of each cluster

Usage

## S3 method for class 'cluscata_liking'
plot(x, DataCata, Dataliking, ngroups=NULL,
 center=TRUE, scale=FALSE,
 sep_graphs=TRUE, Graph_dend=TRUE, Graph_bar=FALSE,
  cex=1,  xlimfreq=c(0,0.6), ylimchangelik=c(-2, 2), ...)

Arguments

x	object of class 'cluscata_liking'.
DataCata	data frame or matrix where the blocks of binary variables are merged horizontally. If you have a different format, see change_cata_format
Dataliking	data frame or matrix where the products are in rows and the assessors in columns
ngroups	number of groups to consider. Default: recommended number of clusters
center	Centering of consumer liking. Default: TRUE
scale	Scaling of consumer liking. Default: FALSE
sep_graphs	logical. Should cata and liking data analyzed separately first?
Graph_dend	logical. Should the dendrogram be plotted? Default: TRUE
Graph_bar	logical. Should the barplot of the difference of the criterion and the barplot of the overall homogeneity at each merging step of the hierarchical algorithm be plotted? Also available after consolidation if Noise_cluster=FALSE. Default: FALSE
cex	numerical. Numeric character expansion factor; multiplied by par("cex") yields the final character size. NULL and NA are equivalent to 1.0.
xlimfreq	vector of 2 values. Used for the graph of the frequency of citations
ylimchangelik	vector of 2 values. Used for the graphs of change in liking
...	further arguments passed to or from other methods

Value
