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
