In daniellyz/MetICA2: Independent component analysis for high-resolution mass-spectrometry based metabolomics

#' Yeast exo-metabolome example data
#'
#' Exo-metabolomic profiles of 15 yeast commercial strains for winemaking. The experiment included 3 biological replicates. Samples were taken at the end of alcoholic fermentationand measured on direct-infusion FT-ICR-MS.

#' @format A two-element list object:
#' \itemize{
#'   \item features: metabolic features detected and extracted. Each feature is represented by a unique ID and a mass (m/z).
#'   \item X: data matrix with 45 rows (samples) and 2700 columns (metabolic features). This is the example data matrix for MetICA simulations.
