Baseline.Correction {NMRS}R Documentation

Baseline Correction

Description

Interactive Baseline Correction of raw spectra based in the FTICRMS package.

Usage

Baseline.Correction(coord)

Arguments

coord Data.frame with the spectral information, where the first column holds the chemical shift positions and the different spectral intensities are in the followings columns

Details

Baseline correction is a very essential step to obtain high quality NMR spectra in some cases. Rolling baselines can make it difficult to identify peaks, as well as introduce significant errors into any quantitative measurements. This function based in the FTICRMS package launches a interactive graphical display to control the individual baseline correction. It computes an estimated baseline curve for a spectrum by a method of Rocke and Xi .

Value

a3 Estimated Baseline
datos Data.frame with the baseline corrected
