Prints an R-script to the screen which can be used for xcms processing

Description

This function prints a script of the optimized findPeaks, retcor and grouping parameters to the screen.

Usage

writeRScript(peakPickingSettings, retCorGroupSettings, nSlaves = 0)

Arguments

peakPickingSettings	The optimized settings for xcms-methods findPeaks.centWave or findPeaks.matchedFilter
retCorGroupSettings	The optimized settings for xcms-methods for retcor.obiwarp and group.density
nSlaves	DEPRECATED

Details

This function prints a script out of the optimized findPeaks, retcor and grouping parameters to the screen.

The function message is used to print the script. For capuring the output capture.output(writeRScript(...), type = "message") might be used.

Value
