#' Cell types of 80 PBMC single cells
#' 
#' A dataset containing the barcodes and cell types of 80 PBMC single cells.

#' @format A tibble containing 80 rows and 2 columns.
#'   Cells are a subsample of the Peripheral Blood Mononuclear Cells (PBMC) 
#'   dataset of 2,700 single cell. Cell types were identified with SingleR.
