generateExprVal.method.playerout {affy} | R Documentation

## Generate an expression value from the probes informations

### Description

Generate an expression from the probes

### Usage

      generateExprVal.method.playerout(probes, weights=FALSE, optim.method="L-BFGS-B")

### Arguments

`probes` | a list of `probes` slots from `PPSet.container`
`weights` | Should the resulting weights be returned ?
`optim.method` | see parameter 'optim' for the function `optim`

### Details

A non-parametrical method to weight each perfect match probe in the set and to compute a weighted mean of the perfect match values. One will notice this method only makes use of the perfect matches. (see function `playerout.costfunction` for the cost function).

### Value

A vector of expression values.
