Proton Nuclear Magnetic Resonance spectra of 40 different wine samples

Description

The original data set consists of Proton Nuclear Magnetic Resonance (NMR) spectra of 40 different wine samples in the spectral region from 6.00ppm to 0.50ppm. This data set corresponds to the region between wavelengths 5.62ppm and 5.37ppm only for which t = 397 measurements are available for each curve. The data has been analyzed in Hubert et al. (2015), see below.

Usage

data(wine)

Format

A three dimensional t = 397 by n = 40 by p = 1 array, with t the number of observed time points, n the number of functional observations and p the number of measurements for every functional observation at every wavelength.
