p2SNR {PANR} | R Documentation

## Translate p-values to Signal-to-Noise Ratios

### Description

The function translate p-values to Signal-to-Noise Ratios based on the fitted mixture model.

### Usage

    p2SNR(object, pval, ...)

### Arguments

`object` | an object of S4 class `BetaMixture`.
`pval` | a numeric or integer specifying the p-value to translate
`...` | not in use, only for further extension.

### Value

The function will return a data frame including p-values, lower and upper quantiles and corresponding Signal-to-Noise Ratios.
