PeakML.Methods.PeakShapeCorrelation: PeakML.Methods.PeakShapeCorrelation

In mzmatch.R: mzmatch and PeakML integration for XCMS.

Description

This function will calculate peak correlation between two chhromatograms.

Usage

PeakML.Methods.PeakShapeCorrelation (chromatogram1,chromatogram2)

Arguments

chromatogram1	Chromatogram from PeakML.Read$chromDataList
chromatogram2	Chromatogram from PeakML.Read$chromDataList

Details

The PeakML file format defines an open and extensible file format for storing extracted hyphenated mass spectrometry data. As such, the format will enable users to store intermediate data in a structured manner, but more importantly, to exchange data between different data analysis software. This will give complete flexible control to the users of data analysis software to cherry pick those components best suited to their needs.

The PeakML.Methods.getGroupAnnotations function allows to access attributes defined in PeakML file.

Value

Vector containing correlation value and p.valu from correlation test.
