How do we feed the rotated loadings obtained through varimax rotation using psych package to hierarchial clustering in the FactomineR package (HCPCC())? I want to use the rotated components instead of the PCA loadings for clustering (hierarchial clustering/ HCPC function) in the FactomineR package but not able to find the code. On another note, can results based on clustering obtained through PCA loadings be enough or it is better to used the rotated loadings on clustering?
