#' IR and NMR Spectra of Serenoa repens (Saw Palmetto) Oil Extracts and
#' Reference Oils
#'
#' A collection of 14 IR and NMR spectra of essential oil extracted from the
#' palm \emph{Serenoa repens} or Saw Palmetto, which is commonly used to treat
#' BPH in men.  The 14 spectra are of different retail samples, and are divided
#' into two categories based upon the label description: adSrE, adulterated
#' extract, and pSrE, pure extract.  The adulterated samples typically have
#' olive oil added to them, which is inactive towards BPH.  There are two
#' additional spectra included as references/outliers: evening primrose oil,
#' labeled EPO in the data set, and olive oil, labeled OO.  These latter two
#' oils are mixtures of triglycerides for the most part, while the SrE samples
#' are largely fatty acids.  As a result, the spectra of these two groups are
#' subtly different.
