leukemia: Leukemia data

Description

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.

Usage

data(leukemia)

Format

A data frame with 38 observations (rows) of 500 variables (columns).

Details

Bone marrow samples obtained from acute leukemia patients at the time of diagnosis.
