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)
