baseline.medianWindow: Median window

In baseline: Baseline Correction of Spectra

Median window

Description

An implementation and extention of Mark S. Friedrichs' model-free algorithm

Usage

baseline.medianWindow(spectra, hwm, hws, end)

Arguments

spectra	Matrix with spectra in rows
hwm	Window half width for local medians
hws	Window half width for local smoothing (optional)
end	Original endpoint handling (optional boolean)

Details

An algorithm finding medians in local windows and smoothing with gaussian weighting

Value

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

Examples

data(milk)
bc.medianWindow <- baseline(milk$spectra[1,, drop=FALSE], hwm=300,
	method='medianWindow')
## Not run: 
	plot(bc.medianWindow)

## End(Not run)
