Given a list/data frame of grouped p-values, selecting thresholds and p-value combining method, retruns adjusted conditional p-values to make decisions

1 2 | ```
cFDR.cp.adjust(pval, t, comb.method = c("Fisher", "Stouffer", "minP"),
make.decision, sig.level)
``` |

`pval` |
the structural p-values, the type should be |

`t` |
the thresholds determining whether the families are selected or not, also affects conditional p-value within families. |

`comb.method` |
p-value combining methods including |

`make.decision` |
logical; if |

`sig.level` |
significant level used to compare with adjusted p-values to make decisions, the default value is 0.05. |

A list of the adjusted conditional p-values, a list of `NULL`

means the family is not selected to do the test in the second stage.
