whitening page on CRAN.

The "whitening" package implements the whitening methods (ZCA, PCA, Cholesky, ZCA-cor, and PCA-cor) discussed in Kessy, Lewin, and Strimmer (2018) as well as the whitening approach to Canonical Correlation Analysis (CCA) allowing negative canonical correlations described in Jendoubi and Strimmer (2019). The package also offers a function to simulate random orthogonal matrices.
