identifyControlBeads: Classify each bead according to its control status

In beadarray: Quality assessment and low-level analysis for Illumina BeadArray data

Description

Using the control annotation specified for the array, the function will classify each bead as belonging to a control group, or as being a regular probe.

Usage

identifyControlBeads(BLData, array = 1, controlProfile = NULL)

Arguments

BLData	a beadLevelData object
array	the numeric id of the array section
controlProfile	an optional control profile data frame

Details

The function requires either that a control profile data frame is specified (This associates probe IDs with their control status - see the example), or that the annotation of the beadLevelData object be set to an array that the package recognises (see getAnnotation). Note that some positive control bead-types may also be functioning 'regular' probes.

Value

a vector of character strings giving the status of each bead
