Description: Implementation of uniformity tests on the circle and
    (hyper)sphere. The main function of the package is unif_test(), which
    conveniently collects more than 35 tests for assessing uniformity on
    S^{p-1} = {x in R^p : ||x|| = 1}, p >= 2. The test statistics are 
    implemented in the unif_stat() function, which allows computing several
    statistics for different samples within a single call, thus facilitating
    Monte Carlo experiments. Furthermore, the unif_stat_MC() function allows
    parallelizing them in a simple way. The asymptotic null distributions of
    the statistics are available through the function unif_stat_distr(). The
    core of 'sphunif' is coded in C++ by relying on the 'Rcpp' package.
    The package also provides several novel datasets and gives the replicability
    for the data applications/simulations in García-Portugués et al. (2021)
