Sanitize spectra — sanitize

This function sanitizes spectra

Usage

sanitize_spectra(spectra, cutoff = 0, dalton = 0.01, polarity = NA, ppm = 10)

Arguments

spectra: Spectra object
cutoff: Absolute minimal intensity
dalton: Dalton tolerance
polarity: Polarity
ppm: PPM tolerance

Value

The sanitized spectra

Examples

data.frame(
  FEATURE_ID = c("FT001", "FT002", "FT003"),
  mz = c(list(123.4567, 234.5678, 345.6789))
