#' Example Single Cell RNA-Seq data in SingleCellExperiment Object, GSE60361
#' subset
#'
#' A subset of 30 cells from a single cell RNA-Seq experiment from Zeisel, et
#' al. Science 2015. The data was produced from cells from the mouse
#' somatosensory cortex (S1) and hippocampus (CA1). 15 of the cells were
#' identified as oligodendrocytes and 15 of the cell were identified as
#' microglia.

#' Example Single Cell RNA-Seq data in SingleCellExperiment Object,

#' @description 
#' https://support.10xgenomics.com/single-cell-gene-expression/datasets/2.1.0/pbmc4k
#' A subset of 390 barcodes and top 200 genes were included in this example.
#' Within 390 barcodes, 195 barcodes are empty droplet, 150 barcodes are cell
#' barcode and 45 barcodes are doublets predicted by scrublet and doubletFinder
#' package. This example only serves as a proof of concept and a tutoriol on how
#' to run the functions in this package. The results should not be used for
#' drawing scientific conclusions.

#' Example Single Cell RNA-Seq data in SingleCellExperiment object, with
#' different batches annotated
#'
#' Two batches of pancreas scRNAseq dataset are combined with their original
#' counts. Cell types and batches are annotated in `colData(sceBatches)`.
#' Two batches came from Wang, et al., 2016, annotated as `'w'`; and Xin, et
#' al., 2016, annotated as `'x'`. Two common cell types, `'alpha'` and
#' `'beta'`, that could be found in both original studies with relatively
#' large population were kept for cleaner demonstration.
