Coarse approximation linear function

1 2 |

`data` |
Matrix or data frame. First column must contain case/control dummy coded variable (if targetVector = "binary"). Otherwise, first column must contain real number vector corresponding to selection variable (if targetVector = "real"). All other columns contain relevant markers. |

`nMarkers` |
Maximum number of markers to include in creation of sum. |

`targetVector` |
Indicate "binary" for target vector with two options (e.g., case/control). Indicate "real" for target vector with real numbers. |

`margin` |
Real number from 0 to 1. Indicates the amount a potential marker must improve the target criterion (Pearson correlation or p-value) in order to add the marker. |

`optimize` |
Criteria to optimize if targetVector = "binary." Indicate "pval" to optimize the p-value corresponding to the t-test distinguishing case and control. Indicate "auc" to optimize the AUC. |

`verbose` |
Logical. Indicate TRUE to print activity at each iteration to console. Defaults to FALSE. |

A data frame containing the chosen markers and their assigned weight (-1 or 1)

The AUC value for the classification

rocPlot. A plot object from ggplot2 for the receiver operating curve.
