DRQualControl: Computing the dynamic range

In RNAither: Statistical analysis of high-throughput RNAi screens

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.
