## Function to compute the Relapse Score as published by Wang et al. 2005

### Description

This function computes signature scores and risk classifications from gene expression values following the algorithm used for the Relapse Score (GENE76) as published by Wang et al. 2005.

### Usage

    gene76(data, er)

### Arguments

`data` | Matrix of gene expressions with samples in rows and probes in columns, dimnames being properly defined.
`er` | Vector containing the estrogen receptor (ER) status of breast cancer patients in the dataset.

### Value

A list with items:

- score Continuous signature scores

- risk Binary risk classification, 1 being high risk and 0 being low risk.
