Not too familiar with the test either, but the same package offers a function frdManyOneNemenyiTest for many to one comparisons that does take into account the alternative parameter (frdManyOneNemenyiTest(y, alternative='greater') and frdManyOneNemenyiTest(y, alternative='less') do give me opposite results as expected) Perhaps I can just use this function in a round-robin fashion to compare all my samples?

Looking at the documentation of the function it doesn't look like alternative is an argument of the function (rather the value of alternative is returned along with other values): rdocumentation.org/packages/PMCMRplus/versions/1.7.1/topics/… I'm not familiar with this test but if the sampling distribution is symmetrical you can just divide the p-value by 2 to get the one-tailed test (provided the sample effect is in the hypothesized direction)
