subtractPeaks.msimat: Remove peaks from an msimat object within specified mass...

In kbseah/mass2adduct: Mass Spectrometry Imaging Molecular Adduct Finder

Description

Remove peaks, e.g. known contaminants, from an msimat object. The peaks are specified by their m/z values, and peak intensities are not taken into account. Mass accuracies (expressed as ppm values) for both the msimat dataset and the removal peaklist must be specified, and will be used to determine the margin of error for excluding a given peak.

Usage

## S3 method for class 'msimat'
subtractPeaks(input, vec, ppm1, ppm2)

Arguments

input	numeric; msimat object containing peaks to be removed
vec	numeric; List of peaks to be removed from d
ppm1	numeric; Mass accuracy for peaklist v1, in ppm
ppm2	numeric; Mass accuracy for peaklist v2, in ppm

Value

msimat object
