OptionalalternativeAlternative hypothesis (unambiguous abbreviations accepted). "greater": the distribution function of x lies
above that of y (statistic D^+); "less": below (D^-). Default "two.sided".
OptionalexactExact p-value. Default: exact for one sample of fewer than 100 values without ties, and for two samples with m n < 10000. The exact two-sided one-sample p-value for D < 1/2 raises a matrix of size 2 floor(n D) + 1 to the n-th power; where that needs more than 2^33 multiply-adds (m 783 at n 1023, about 4 s) it is a RangeError (R computes it however long it takes).
