ct.inputCheck {gCrisprTools} | R Documentation

## Check compatibility of a sample key with a supplied object

### Description

For many gCrisprTools functions, a sample key must be provided that specifies sample mapping to experimental groups and specifies which of these contains control samples. This function checks whether the specified sample key is of the proper format and has properties consistent matching the specified object.

### Usage

    ct.inputCheck(sampleKey, object)

### Arguments

`sampleKey` | A named factor, where the `levels` indicate the experimental replicate groups and the `names` match the `colnames` of the expression matrix contained in `object`. The first `level` should correspond to the control samples, but obviously there is no way to algorithmically control this.
`object` | An `ExpressionSet`, `EList`, or matrix.

### Value

A logical indicating whether the objects are compatible.

### Examples

    data('es')
    library(limma)
    library(Biobase)

    #Build the sample key
    sk <- relevel(as.factor(pData(es)$TREATMENT_NAME), "ControlReference")
    names(sk) <- row.names(pData(es))
    ct.inputCheck(sk, es)
