| PeakML.Isotope.getRatioMtxList {mzmatch.R} | R Documentation |
Returns the matrix for each peak group, containing the ratio of labelled vs unlabelled signals for each replicate normalized to one along the columns and isotopes along the columns.
PeakML.Isotope.getRatioMtxList(intList, sampleGroups, useArea, metName="")
intList |
list containing intensities of isotopes. |
sampleGroups |
The sample groups. |
useArea |
TRUE will sum up all intensities to give area under the curve, FALSE gives maximum intensities. |
metName |
name of the metabolite to give the column name of the matrix. |
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 contains a set of R functions that will enable end users to rapidly write scripts to manipulate PeakML files.
