NCI microarray data. The data contains expression levels on 6830 genes from 64 cancer cell lines. Cancer type is also recorded.
The format is a list containing two elements:
data is a 64 by 6830 matrix of the expression values while
labs is a vector listing the cancer types for the 64 cell lines.
The data come from Ross et al. (Nat Genet., 2000). More information can be obtained at http://genome-www.stanford.edu/nci60/
