#' Raman.train: Raman Spectroscopy on Fish Oil
#'
#' This data set contains Raman spectra for 30 salmon oil samples extracted from
#' farmed salmon, \emph{Salmo salar}. The Iodine number, which is connected to
#' the degree of unsaturation in the fatty acids, is reported.

#' @details
#'
#' The wavelengths used in the Raman spectroscopy were -20 cm\eqn{^{-1}} – 3450
#' cm\eqn{^{-1}}. Wavelengths before 790 cm\eqn{^{-1}} and after 3050
#' cm\eqn{^{-1}} are not included in this data.
#'
#' The Raman data with a total of 45 observations was split into this training
#' data with 30 observations and a test data set with the remaining 15
#' observations.
