#' NCI60: Gene Expression in Cancer Cell Lines
#'
#' This is NCI microarray data and consists of 6830 gene expression measurements
#' for each of 64 cancer cell lines derived from 14 types of human tumours. The
#' researchers wanted to classify the cell lines based on the observed gene
#' expression patterns.
#'
#' @format A data frame with 64 observations (rows) and 6832 variables
#' (columns).
