Description: Kernel estimation of a univariate probability density and
        of its derivatives of any order r, with data-driven bandwidth
        selection. Provides the kernel estimator of the derivative of
        order r, the kernels, their derivatives and convolutions, and
        eight bandwidth selectors: the asymptotic MISE rule (AMISE),
        and unbiased (UCV), biased (BCV1, BCV2), complete (CCV),
        modified (MCV), trimmed (TCV), smoothed (SCV) and
        maximum-likelihood (MLCV) cross-validation. Supports ten named
        kernels (Gaussian, Epanechnikov, uniform, triangular, biweight,
        triweight, tricube, cosine, Silverman, logistic) and the power
        family Pow(s,t), c(1-|x|^s)^t on [-1,1]. Results are S4 objects
        with 'ggplot2' graphics; the O(n^2) criteria are computed in
        C++ ('Rcpp') with 'OpenMP' parallelism. Includes five example
        samples from Marron and Wand (1992) normal mixtures, a vignette
        and demos. Companion to Guidoum (2020)
