DRQualControl {RNAither} | R Documentation

## Computing the dynamic range

### Description

Computes the dynamic range per plate for a complete dataset file and plots the results.

### Usage

    DRQualControl(header, data, nbLinesHeader, channel, plotTitle, showPlot)

### Arguments

`header` | the header of a dataset file generated with `generateDatasetFile`
`data` | an R data frame generated with `generateDatasetFile`
`nbLinesHeader` | typically 3
`channel` | A character string specifying the name of the column containing the values for computing the dynamic range, e.g. `"SigIntensity"`
`plotTitle` | the plot title
`showPlot` | 0 or 1. 1 will open one or several plot windows in the R GUI, 0 will only save the plot(s) without opening windows

### Value

Returns the dynamic range for each plate in the shell and saves them in a text file. The name of the text file will be the concatenation of the experiment name specified in the header and the character string "DR.txt".

Shows a plot of the dynamic range values and saves it as a pdf file under the experiment name specified in the header concatenated with the function argument `plotTitle`.
