Description

NCI microarray data. The data contains expression levels on 6830 genes from 64 cancer cell lines. Cancer type is also recorded.

Usage

NCI60

Format

The format is a list containing two elements: data and labs.

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.
