## S4 method for signature 'PeakList,numeric,numeric'
addPeaks(object, mzs, width, ...)

Arguments

object	PeakList object
mzs	numeric vector M/z's where peaks shall be added
width	fixed value to add (m/z)
...	further args

Value

object updated PeakList object

Examples

library(tofsimsData)
data(tofsimsData)
testPeakList<-PeakList(analysisName = analysisName(testSpectra),
instrument = instrument(testSpectra),
nz = nz(testSpectra),
calibration = calibration(testSpectra),
calibPoints = calibPoints(testSpectra),
mz = mz(testSpectra),
peakIDs = NULL,
peakMzs = NULL)
par(mfcol=c(1,2))
plot(testPeakList, mzRange=c(25,32), type = 'l')
testPeakList<-addPeaks(testPeakList, mzs=26:31, width=0.4)
