In multiple testing problem, the adjusted P-values correspond to test statistics can be used with any fixed alpha to dertermine which hypotheses to be rejected.

`teststats` |
The k-vector of test statistics, |

`alternative` |
The alternative hypothesis: "U"=upper one-sided test (default); "L"=lower one-sided test; "B"=two-sided test. For lower one-sided tail test, use the negations of each of the test statistics. |

`df` |
Degree of freedom of the t-test statistics. When (approximately) normally distributed test statistics are applied, set df=Inf (default). |

`corr` |
Specified for equally correlated test statistics, which is the common correlation between the test statistics, default=0.5. |

`corr.matrix` |
Specified for unequally correlated test statistics, which is the correlation matrix of the test statistics, default=NA. |

Return a LIST containing:

`"ordered test statistics"` |
ordered test statistics from largest to smallest |

`"Adjusted P-values of ordered test statistics"` |
adjusted P-values correspond to the ordered test statistics |
