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.
