-Description: Implements non-parametric tests from Higgins (2004, ISBN:0534387756), including one-sample, two-sample, k-sample, paired comparison, randomized complete block design, correlation and contingency table tests. Built with 'Rcpp' for efficiency and 'R6' for flexible, object-oriented design, the package provides a unified framework for performing or creating custom permutation tests.
