Description: Nonparametric smoothing methods for density and regression
        estimation and inference with circular data. The package
        provides kernel density estimation along with inferential tools
        such as circular SiZer for feature significance, mode
        estimation, and modal clustering. It includes multiple methods
        for selecting the smoothing parameter, allowing users to
        optimize the trade-off between bias and variance. Various
        plotting functions help visualize estimated densities, modes,
        clusters, and significance features. For regression, the
        package implements nonparametric estimation of the mean
        regression function as well as other conditional
        characteristics, including modal regression and generalized
        regression. Bandwidth selection is also supported in the
        regression context, and testing procedures are available to
        assess structural features or effects in circular regression
        models.
