Local baseline correction

Description

Substract a baseline either through 1 or 2 points

Usage

localBaselineCorrect(object, baseWavelengths = NULL)

Arguments

object

SpectraInTime-class

baseWavelengths

Examples

spectra              <-  getSpectraInTimeExample()
spectraConstCorrect  <-  localBaselineCorrect( spectra , baseWavelengths = 240  )
spectraLinCorrect    <-  localBaselineCorrect( spectra , c( 250 , 330 )  ) 

plot( spectra )
plot( spectraConstCorrect )
plot( spectraLinCorrect )
