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

### Description

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

### Usage

    SNR2p(object, SNR, ...)

### Arguments

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

### Value

The function will return a data frame including SNRs, lower and upper quantiles and corresponding p-values.
