Annotation {beadarray} | R Documentation

## Storage of annotation information

### Description

An interface to set or retrieve information about the annotation of a `beadLevelData` or `ExpressionSetIllumina` object.

### Usage

        suggestAnnotation(data,verbose=FALSE)
        annotation(object,...)

### Arguments

`data` | An object of class `beadLevelData-class`

.

`verbose` | If TRUE, report overlaps with known platforms
`object` | Either a `beadLevelData-class` or `ExpressionSetIllumina-class`
`...` | Extra arguments used by annotation

### Details

A character string is used to specify the annotation with the currently supported values being; Humanv4, Humanv3, Humanv2, Humanv1, Mousev2, Mousev1, Mousev1p1 and Ratv1. This string is used within beadarray to retrieve control probe IDs within particular QC functions.

The `suggestAnnotation` function tries to determine a suitable value for a `beadLevelData-class` based on the probe IDs and compiled list of IDs from all expression platforms. This is based on the percentage of IDs on the array that overlap with IDs from known platforms. The platform with highest overlap is chosen.

    data(exampleSummaryData)

    annotation(exampleSummaryData)

    annotation(exampleBLData) <- "Humanv1"

    }
