## Accessors and replacement methods for the PM/MM/BG matrices.

### Description

Accessors and replacement methods for the PM/MM/BG matrices.

### Usage

    mm(object, subset = NULL)
    pm(object, subset = NULL, ...)
    bg(object, subset = NULL)
    mm(object)<-value
    pm(object)<-value
    bg(object)<-value

### Arguments

`object` | `FeatureSet` object.
`subset` | Not implemented yet.
`value` | `matrix` object.
`...` | Extra arguments for future implementation.

### Details

For all objects but `TilingFeatureSet2`, these methods will return matrices. In case of `TilingFeatureSet2` objects, the value is a 3-dimensional array (probes x samples x channels).

### Examples

    if (require(maqcExpression4plex) & require(pd.hg18.60mer.expr)){
    xysPath <- system.file("extdata", package="maqcExpression4plex")
    xysFiles <- list.xysfiles(xysPath, full.name=TRUE)
    ngsExpressionFeatureSet <- read.xysfiles(xysFiles)
    pm(ngsExpressionFeatureSet)[1:10,]
    }
