linedistance {Comp2ROC} | R Documentation |

## Intersection Points

### Description

This function allows to calculate the intersection points between the ROC curve and the sampling lines. Also calculates the distance between this points and the reference point.

### Usage

```
linedistance(curve.fpr, curve.tpr, curve.segslope, curve.slope, line.slope, ref.point)
```

### Arguments

`curve.fpr` |
False positive rate vector with all points of the given Curve |

`curve.tpr` |
True positive rate vector with all points of the given Curve |

`curve.segslope` |
Vector with all segments slope of the ROC curves |

`curve.slope` |
Vector with all the slope of all segments that connect the ROC curve with the reference point |

`line.slope` |
Vector with the slope of all sampling lines |

`ref.point` |
Reference point where we start drawing the sampling lines |

### Value

This function returns a list with:

`dist` |
Vector with distances between the intersection points and the reference points |

`x` |
Vector with all x coordinates of intersection points |

`y` |
Vector with all y coordinates of intersection points |
