In tofsims: Import, process and analysis of Time-of-Flight Secondary Ion Mass Spectrometry (ToF-SIMS) imaging data

Description

Generic method for unitMassPeaks

Usage

unitMassPeaks(
  object,
  mzRange,
  widthAt,
  factor,
  upper = NULL,
  lower = NULL,
  ...
)

## S4 method for signature 'MassSpectra,numeric,numeric'
unitMassPeaks(
  object,
  mzRange,
  widthAt,
  factor,
  upper = NULL,
  lower = NULL,
  ...
)

Arguments

object	object of class MassSpectra
mzRange	vector numeric with lower and upper mass range limit for which to set unit mass peaks
widthAt	vector numeric two mass values at which to sample for peak width
factor	vector numeric two values summing up to 1 for setting assymetric peak width limits
upper	vector numeric upper peak width limits
lower	vectpr numeric lower peak width limits
...	additional args

Value

object of class PeakList with unit mass peaks

Examples

library(tofsimsData)
data(tofsimsData)
testSpectra <- calibPointNew(testSpectra, mz = 15, value = 15.01551)
testSpectra <- calibPointNew(testSpectra, mz = 181, value = 181.0228)
testSpectra <- recalibrate(testSpectra)
testSpectra <- unitMassPeaks(testSpectra, mzRange = c(1,200), widthAt = c(15, 181), 
factor = c(0.4, 0.6), lower = c(14.97, 15.05), upper = c(180.84, 181.43))
plot(testSpectra, mzRange = c(1,200), type = 'l')
