The Mann-Whitney-Wilcoxon test that we presented in the previous recipe, can be extended to multiple groups (not just 2 was before). For one-way Analysis Of Variance (ANOVA), the test that is used is called Kruskal-Wallis; we have the kruskal.test() function in base R.
For nonparametric two-way ANOVA, the Scheirer-Ray-Hare test can be used; however, the documentation is scarce, and it is not frequently used.
