make_spectrum_peakpick: make_spectrum_peakpick

In davidsbutcher/abundancer: Determine Abundances of 12C and 14N from Protein Mass Spectra

Description

make_spectrum_peakpick

Usage

make_spectrum_peakpick(
  MSspectrum = NULL,
  mz = NULL,
  intensity = NULL,
  SNR = 10,
  method = "MAD",
  refineMz = "kNeighbors",
  k = 2,
  binSize = 0.05
)

Arguments

MSspectrum	An MSnbase Spectrum1 object.
mz	A numeric vector containing m/z values for a spectrum.
intensity	A numeric vector containing intensity values for a spectrum.
SNR	Signal-to-noise cutoff to use for peak picking. See ?MSnbase::pickPeaks.
method	Method to use for peak picking. See ?MSnbase::pickPeaks.
refineMz	Method for m/z refinement for peak picking. See ?MSnbase::pickPeaks.
k	Number of neighboring signals to use for m/z refinement if refineMz = "kNeighbors". See ?MSnbase::pickPeaks.
binSize	Bin size to use for peak binning prior to comparing spectra. See ?MSnbase::bin.
