#' Obtain the Lawlor pancreas data
#'
#' Provides the human pancreas single-cell RNA-seq data from Lawlor et al. (2017).
#'
#' @details
#' Column metadata is provided in the same form as supplied in GSE86469. 
#' This contains information such as the cell type labels and patient status.
#'
#' All data are downloaded from ExperimentHub and cached for local re-use.
#' Specific resources can be retrieved by searching for \code{scRNAseq/lawlor-pancreas}.
#'
#' @return A \linkS4class{SingleCellExperiment} object with a single matrix of read counts.
