Confidence curves are a way to show the confidence in an estimate computed from sample data. They are useful because they show all confidence levels simultaneously, thereby giving a good sense of the accuracy of the estimate, without forcing the researchers to make a more or less arbitrary choice for one confidence level.

`metric` |
The metric, currently only 'd' (Cohen's |

The value for which to create the confidence curve plot. |

The sample size for which to create the confidence curve plot. If |

`conf.level` |
The confidence level for which to create the confidence curve plot. If |

`wRange` |
The range of 'half-widths', or margins of error, to plot in the confidence curve plot if no sample size is specified (if |

`curveSize` |
The line size of the confidence curve line. |

`curveColor` |
The color of the confidence curve line. |

`confRange` |
The range of confidence levels to plot. |

`confLines` |
If a traditional confidence curve is generated, lines can be added to indicate the metric values corresponding to the lower and upper confidence interval bounds. |

`confLineColor` |
If confidence lines are added (see |

`confLineSize` |
If confidence lines are added (see |
