%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 30 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 to several 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
application in García-Portugués, Navarro-Esteban and Cuesta-Albertos
(2023) <arXiv:2008.09897>.
