SPCA 2.0 calculates PCA using Correlation coefficient of Pearson, in addition there is clustering of observations by three methods: KNN, K-means and Hierarchical Clustering.
The code displays main calculations of PCA : Correlation matrix (using c.pearson) and computes eigenvectors and eigenvalues.
in second part: the package displays Clustering of Observations according three methods: KNN, K-means and Hierarchical clustering (HC)
