Glass data
Description
Glass data of Lemberge et al. (2000) containing Electron Probe X-ray Microanalysis (EPXMA) intensities for different wavelengths of 16–17th century archaeological glass vessels. This dataset was also used in Hubert et al. (2005) and Hubert et al. (2016).
Usage
Glass
Format
A data frame with columns:
A data frame with 180 observations and 750 variables. These variables correspond to
EPXMA intensities for different wavelengths and are indicated by V1, V2, ..., V750.
