## Gets the raw intensity data from a BeadLevelList object

### Description

Retrieves the raw intensity information from a given array stored in a `BeadLevelList` object.

### Usage

    getArrayData(BLData,which="G",array=1,log=TRUE)

### Arguments

`BLData` | `BeadLevelList`
`which` | character string specifying which intensities to obtain. Possibilities are `"ProbeID"`, `"GrnX"`, `"GrnY"`, `"G"`, `"Gb"` for single channel data and additional columns `"R"` and `"Rb"` for two-colour data
`array` | numeric value giving the array we are interested in
`log` | if TRUE log2 of the raw intensities are returned

### Value

A vector containing the intensities
