#' @description An example metabolomics analysis of human plasma from
#' Red Cross and CHEAR cohorts, plus pooled aliquots and blanks, acquired with
#' a 30 minute total Reversed-Phase Liquid Chromatography and a QTOF-MS
#' instrument in the positive ionization mode.

#' @title Three LC-MS Metabolomics Batch Datasets
#'
#' @description An example multi-batch LC-MS metabolomics analysis of human
#' plasma, used to demonstrate \code{\link{batchCombine}}. Due to the large size
#' of the full experimental data, only three of the batches are loaded here with
#' a subset of the samples and features from each batch.
