## Calculate normalized betas from exprmethy450 of Illumina 450K methylation arrays

### Description

Quantile normalize betas from exprmethy450 objects

### Arguments

`bn` | An exprmethy450 object.
`fudge` | value added to total intensity to prevent denominators close to zero when calculating betas

### Details

betaqn quantile normalizes betas

### Value

exprmethy450 object of the same shape and order as bn.

### methods

betaqn( bn ) fuks( bn )
