While using the Hodges Lehmann Mean in DescTools (DescTools::HodgesLehmann), I found that it generated incorrect answers (see <https://github.com/AndriSignorell/DescTools/issues/97> https://github.com/AndriSignorell/DescTools/issues/97). The error is driven by the existence of tied values forcing wilcox.test in Base R to switch to an approximate algorithm that retur...

...: these can force R to use a normal approximation even in low-sample cases. - degenerate two-sample tests (`max(x)==min(x)` and `max(y)==min(y)`): this produces an error due to an unhandled edge case. This particular issue has caused problems for the DescTools package, which recently reimplemented HodgesLehmann due to inaccurate results in base R. At the very least, warnings should probably be added so that users don?t misinterpret these results. Better still would be to just fix these cases, but I haven?t dug super deep into the codebase yet, so I?m not completely sure how difficult that would be. Detai...
