Get average m/z and intensity values for multiple mass scans

Return full-resolution averaged data from multiple mass scans.

Methods

object = "xcmsRaw"

getSpec(object, ...)

Arguments

object

the xcmsRaw object

...

arguments passed to profRange used to sepecify the spectral segments of interest for averaging

Details

Based on the mass points from the spectra selected, a master unique list of masses is generated. Every spectra is interpolated at those masses and then averaged.

Value

A matrix with two columns:

mz

m/z values

intensity

intensity values
