Description

Robust rank order test

Rro.test(x1, y1)

y1	Second numerical variable

Details

Robust rank order test (modification of Wilcoxon test for samples with contrasting variation), a variant of Fligner-Policello test.

Alternatives: robustrank::mod.wmw.test() (probably more sophisticated); npsm::fp.test(); NSM3::pFligPoli() (very advanced, with possibilities of exact and Monte Carlo testing); RVAideMemoire::fp.test() (developed in the way similar to most base R tests, probably the best alternative).
