ir
A sample object of class ir
. The data set
contains ATR-MIR spectra for a set of organic reference materials
along with their metadata (types of samples and a description) and
accessory data (Klason lignin mass fraction and holocellulose mass fraction).
ir_sample_data
A data frame with 58 rows and 7 variables:
An integer vector with a unique id for each spectrum.
A character vector with a unique id for each sample.
A character vector containing class labels for the types of reference materials.
A character vector containing comments to each sample.
A numeric vector with the mass fractions of Klason lignin in each sample.
A numeric vector with the mass fractions of holocellulose in each sample.
