MassSpecMethod_CorrectSpectraBaseline_airpls S7 class — MassSpecMethod_CorrectSpectraBaseline_airpls • StreamFind

Performs baseline correction using adaptive iteratively reweighted Penalized Least Squares (airPLS) based on the algorithm from Zhi-Min Zhang.

Usage

MassSpecMethod_CorrectSpectraBaseline_airpls(
  lambda = 10,
  differences = 1,
  itermax = 20
)

Arguments

lambda: Numeric (length 1) with the smoothing intensity. the higher the lambda the higher the smoothing.
differences: Integer (length 1) indicating the order of the difference of penalties
itermax: Integer (length 1) with the maximum number of iterations.

Value

A MassSpecMethod_CorrectSpectraBaseline_airpls object.
