| multiplePeaks {MetaNetwork} | R Documentation |
Example of the Multiple Peaks report that relates metabolites represented
by multiple mass peaks (because of isotopic or differential charges) for
peaks2 example data set using information from traits2.
This report can be produced
by functions findMultiplePeaks or MetaNetwork.
