nci60-drugtox: NCI-60 Drug Toxicity Data

#' NCI 60 Cell-Drug Toxicity
#'
#' Negative log10 (GI50) values of sulforhodamine B assay for ~ 50K compounds, 
#' including more than 20,000 that passed quality control, 158 Food and Drug 
#' Administration approved and 79 clinical trial drugs. Higher values equate 
#' to higher sensitivity of cell lines.
