## Colon Cancer Microarray Data

### Description

The `colon` data contains two objects: `colon.x`, microarray expression data for 62 colon cancer samples and `colon.y`, the class labels for these samples.

### Usage

    data(colon)

### Format

An expression data matrix (62x2000) `colon.x` and a class label vector (62) `colon.y` for 62 samples.

### Details

`colon.y` is the class labels of the 62 samples. `colon.x` is the microarray expression data matrix with each row representing a sample.
