puttingAllTogether: Example of strategy to find signature from different seeds at...

In geneSignatureFinder: A Gene-signatures finder tools

Description

This function has been designed to show how to put the functions of the package in sequence in order to analyse microarray data for signatures. Given this function is an example, and can be run for small microarray data, the user is invited to a reverse engineering task (start by typing "puttingAllTogether") in order to define a procedure for more complex analysis sessions.

Usage

puttingAllTogether(workingFile = "", nchips = 2, alpha = 0.05,
                 saveSurvivalCurvesPlot = FALSE,
                 saveIndividualSignature = FALSE, 
                 saveImportancePlot = FALSE)

Arguments

workingFile	prefix string for the log file and other output
nchips	see the NCPUS() function for details; it has to be set to the number of cpu's to use if useCpuCluster = TRUE
alpha	see the BHcorrection() function
saveSurvivalCurvesPlot	if TRUE a plot of the two survival curves of the signature are stored in a .pdf file in the working directory
saveIndividualSignature	if TRUE a .RData file is stored in the working directory with the result of the signatureFinder() function
saveImportancePlot	if TRUE a plot of the importances of the genes in the signature are stored in a .pdf file in the working directory

Details

The plotting of the figures may not work if a graphical device is not instantiated.

Value

Different files can be found in the getwd() directory.
