OptionalalternativeAlternative hypothesis (unambiguous abbreviations accepted). Default "two.sided".
OptionalconfCompute a confidence interval for the ratio of scales and its estimate (R's conf.int). Default false.
OptionalconfConfidence level of the interval. Default 0.95.
OptionalexactExact p-value. Default: exact when both samples have fewer than 50 values and there are no ties. The exact distribution keeps 2 (m + 1) (floor((m + n + 1)^2 / 4) + 1) doubles and makes m + n passes over half of them; beyond 2^24 doubles or 2^32 steps (m = n = 203, or m = 1 and n = 2047) it is a RangeError (R computes it however large).
