`x, q` |
vector of quantiles. |

`nu, sigma` |
positive valued degrees of freedom and scale parameters. |

`log, log.p` |
logical; if TRUE, probabilities p are given as log(p). |

`lower.tail` |
logical; if TRUE (default), probabilities are |

`p` |
vector of probabilities. |

`n` |
number of observations. If |

If *X* follows t distribution parametrized by degrees of freedom *ν*
and scale *σ*, then *|X|* follows half-t distribution parametrized
by degrees of freedom *ν* and scale *σ*.
