The chemometrics near-infrared (NIR) data set

Description

The chemometrics near-infrared (NIR) data set has 202 observations and 2801 variables: 2800 near-infrared wavelength measures and 1 class variable. The data were obtained from the analysis of three types of textiles. The data set was first introduce in Devos et al. (2009) <doi:10.1016/j.chemolab.2008.11.005>.

Usage

data("velibCount")

Format

A data frame with 202 observations and 2801 variables. The first variable indicates the class-memberships of the observations.
