In ir: Functions to Handle and Preprocess Infrared Spectra

Sample object of class ir

Description

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).

Usage

id_sample

A character vector with a unique id for each sample.

sample_type

A character vector containing class labels for the types of reference materials.

sample_comment

A character vector containing comments to each sample.

klason_lignin

A numeric vector with the mass fractions of Klason lignin in each sample.

holocellulose

A numeric vector with the mass fractions of holocellulose in each sample.
