agep {wateRmelon} | R Documentation

## Age Prediction from methylomic expression data

### Description

Predict age of samples using Horvath's Coefficients

### Usage

    agep(betas, coeff=NULL, verbose=FALSE,...)

### Arguments

`betas` | Matrix of betas or MethyLumiSet or MethylSet object.
`coeff` | If NULL, will default to Horvath's coefficients. Otherwise can be supplied with vector of own coefficients with an intercept as first element.
`verbose` | If TRUE, agep will additionally print out names of probes per sample that are missing from coefficient list within supplied beta matrix.
`...` | To pass to arguments to downstream functions to specify adult.age

### Value

Returns matrix of predicted ages per sample.
