ClustOfVar (version 1.1)

plot.clustvar: Plot loadings in each cluster.

Description

Plot dotchart with the "loadings" of the variables in each cluster. The loading of a numerical variable is the correlation between this variables and the synthetic variable of its cluster. The loading of the level of a categorical variable is the mean value of the synthetic variable of the cluster on observations having this level.

Usage

# S3 method for clustvar
plot(x, ...)

Arguments

x

an object of class clustvar obtained with cutreevar or kmeansvar.

…

Further arguments to be passed to or from other methods. They are ignored in this function.

Value

coord.quanti

coordinates of quantitative variables belonging to cluster k on the synthetic variable associate to the same cluster k

coord.levels

coordinates of levels of categorical variables belonging to cluster k on the synthetic variable associate to the same cluster k

Examples

# NOT RUN {
data(wine)
X.quanti <- PCAmixdata::splitmix(wine)$X.quanti
X.quali <- PCAmixdata::splitmix(wine)$X.quali
tree <- hclustvar(X.quanti,X.quali)
tree.cut<-cutreevar(tree,6)

#plot of scores on synthetic variables
res.plot <- plot(tree.cut)
res.plot$coord.quanti
res.plot$coord.levels
# }
