how to cut the dendrogram with VARCLUS in R (package Hmisc)

I want to perform variable clustering using the varclus() function from Hmisc package. However I do not know how to put clusters of variables into a table if I cut the dendrogram into 10 clusters of variable.

I used to use

groups <- cutree(hclust(d), k=10)

to cut dendrograms of individuals but it doesn't work for variables.

Expanding on @Anatoliy's comment, you indeed use the same cutree() function as before because the clustering done in varclus() is actually done by the hclust() function.

When you use varclus() you're creating an object of class varclus that contains a hclust object - which can be referenced by using $hclust.

Example:

x <- varclus(d)
x_hclust <- x$hclust  ## retrieve hclust object

groups <- cutree(x_hclust, 10)
