glass: EXPMA spectra of glass samples

Description

The glass data set studied by Lemberge et al. (2000) consisting of 180 different 16-17th century archaeological glass samples.Electron Probe X-ray Microanalysis (EPXMA) intensities across \(750\) different wavelengths are recorded using a Jeol JSM 6300 scanning electron microscope equipped with an energy-dispersive Si(Li) X-ray detection system (SEM-EDX).

Usage

data("glass")

Format

A three dimensional \(t = 750\) by \(n = 180\) by \(p = 1\) array.
