In MassArray: Analytical Tools for MassArray Data

Description

Function to calculate ratio of salt adduct peak heights to reference/unmodified peaks

Usage

List of MassArrayPeak objects comprising complete spectral data

Details

Salt adducts (either Na or K) are identified and compared to each of their unmodified reference peaks

Value

Returns a list of numerical values corresponding to the ratios of salt adduct peak heights to their unmodified reference peaks
