This data set represents mRNA expression of 500 genes in 38 patient cases of leukemia. These 38 cases fall into 3 subtypes: AML (11), T-lineage ALL (8) and B-lineage ALL (19). The set was obtained by removing 499 genes from Golub's leukemia data, to facilitate the execution of examples for this package.
