colon: Gene expression data from colon-cancer patients
Description
The data file contains gene expression data of 62 samples (40 tumor samples,
22 normal samples) from colon-cancer patients analyzed with an Affymetrix
oligonucleotide Hum6000 array.
Arguments
Format
A list of 2 variables included in colon:
X: a 62-by-2000 matrix that records the gene expression data.
Used as design matrix.
y: a binary vector of length 62 recording the sample status: 1 =
tumor; 0 = normal. Used as response vector.
