fdrThreshold {BioNet} | R Documentation

## Calculate p-value threshold for given FDR

### Description

The function calculates the p-value threshold tau for a given false discovery rate. Tau is used for the scoring function.

### Usage

    fdrThreshold(fdr, fb)

### Arguments

`fdr` | False discovery rate.
`fb` | Model from the beta-uniform mixture fitting.

### Value

P-value threshold tau.
