%description
Implementation of a Principal Component Analysis (PCA) in the torus via
density ridge estimation. The main function, ridge_pca(), obtains the
relevant density ridge for bivariate sine von Mises and bivariate wrapped
Cauchy distribution models and provides the associated scores and variance
decomposition. Auxiliary functions for evaluating, fitting, and sampling
these models are also provided. The package provides replicability to
García-Portugués and Prieto-Tirado (2023)
