Golub data set from CoXpress paper by Michael Watson.
This is a data.frame of AML/ALL leukaemia microarray study, originally from Golub et al Science 286:531 (1999). It comprises gene expression measurements from 38 tumor mRNA samples, including 27 cases of acute lymphoblastic leukemia (ALL) and 11 cases of acute myeloid leukemia (AML). The HU6800 Affymetrix array, which contains 6,800 probe sets, was used. The dataset was filtered to remove genes with negative values in any sample, resulting in a final set of 2,568 genes.
