Combine Spectra by Collision Energy

Combines spectra that share the same collision energy using a TIC-weighted peak combination method. This is useful for merging technical replicates or averaged spectra at each collision energy level.

Usage

combineSpectra_groupby_ce(sp, minProp = 0.5, ppm = 10, plot = F, ...)

Arguments

sp

A Spectra object to combine.

minProp

Numeric between 0 and 1. Minimum proportion of spectra that must contain a peak for it to be retained in the combined spectrum. Default is 0.5.

ppm

Numeric. Parts per million tolerance for grouping peaks. Default is 10.

plot

Logical. If TRUE, generates plots of the combination results. Default is FALSE.

...

Additional arguments passed to Spectra::combineSpectra().

Value

A Spectra object with combined spectra for each unique collision energy.
