baseline.fillPeaks: Fill peaks

In baseline: Baseline Correction of Spectra

Fill peaks

Description

An iterative algorithm using suppression of baseline by means in local windows

Usage

baseline.fillPeaks(spectra, lambda, hwi, it, int)

Arguments

spectra	Matrix with spectra in rows
lambda	2nd derivative penalty for primary smoothing
hwi	Half width of local windows
it	Number of iterations in suppression loop
int	Number of buckets to divide spectra into

Details

In local windows of buckets the minimum of the mean and the previous iteration is chosen as the new baseline

Value

baseline	Matrix of baselines corresponding to spectra spectra
corrected	Matrix of baseline corrected spectra

Examples

data(milk)
bc.fillPeaks <- baseline(milk$spectra[1,, drop=FALSE], lambda=6,
	hwi=50, it=10, int=2000, method='fillPeaks')
