Get correlation groups according to VarClus based on the absolute Spearman correlation coefficients between metrics

This function makes life simple by providing a VarClus.

get.vc.correlation.groups(dataset, metrics, similarity = "spearman",
  varclus.threshold = 0.7)

Arguments

dataset	a data frame for data
metrics	a vector of characters or a vector of characters for independent variables
similarity	a character for similarity measures (e.g., Spearman rank correlation), default = spearman
varclus.threshold	a numeric for correlation coefficient threshold value
