OptionalconfConfidence interval [lower, upper] (R's conf.int).
OptionalconfConfidence level of confInt (R's attr(conf.int, "conf.level")).
OptionalestimateEstimate(s) of the parameter being tested (R's estimate).
OptionalestimateName(s) of estimate (R's names(estimate)), e.g. "mean of x".
Description of the test, as R's method (e.g. "Welch Two Sample t-test").
OptionalnullValue of the parameter under the null hypothesis (R's null.value).
OptionalnullName of nullValue (R's names(null.value)), e.g. "difference in means".
Degrees of freedom (parameterName is "df").
OptionalparameterName of parameter (e.g. "df").
p-value of the test (R's p.value).
Value of the test statistic (R's statistic).
Name of the test statistic (e.g. "t", "X-squared", "V", "W").
R's warnings, each once, in R's order (an empty array when there are none).
Result of a k-sample test with a chi-squared statistic. Has no
alternative, as R returns none.
