plot.clustvar {ClustOfVar} | R Documentation |
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 class 'clustvar'
plot(x, ...)
Arguments
x |
an object of class |
... |
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
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
