## Converting methylation signals to ratios (Beta or M-values)

### Description

Converting methylation data from methylation and unmethylation channels, to ratios (Beta and M-values).

### Usage

    ## S4 method for signature 'MethylSet'
    ratioConvert(object, what = c("beta", "M", "both"), keepCN = TRUE, ...)
    ## S4 method for signature 'GenomicMethylSet'
    ratioConvert(object, what = c("beta", "M", "both"), keepCN = TRUE, ...)

### Arguments

`object` | Either a `MethylSet`, or a `GenomicRatioSet`.
`what` | Which ratios should be computed and stored?
`keepCN` | A logical, should copy number values be computed and stored in the object?
`...` | Passed to `getBeta`, `getM` methods.

### Value

An object of class `RatioSet` or `GenomicRatioSet`.

### See Also

`RatioSet` or codeGenomicRatioSet for the output object and `MethylSet` or codeGenomicMethylSet for the input object.

### Examples

    if (require(minfiData)) {
      ## MsetEx.sub is a small subset of MsetEx;
      ## only used for computational speed.
      RsetEx.sub <- ratioConvert(MsetEx.sub, keepCN = TRUE)
      }
