`formula` |
a two-sided linear formula object describing the model to be fitted, with the response on the left of a ~ operator and the terms, separated by + operators, on the right. |

`link` |
a glm link function for binary outcomes. Must be a function name. Available options: "RRlink.logit", "RRlink.probit", "RRlink.cloglog" and "RRlink.cauchit" |

`item` |
optional item identifier for long-format data. |

`RRmodel` |
the Randomized Response model, defined per case. Available options: "DQ", "Warner", "Forced", "UQM", "Crosswise", "Triangular" and "Kuk" |

`p1` |
the Randomized Response parameter p1, defined per case. Must be 0 <= p1 <= 1. |

`p2` |
the Randomized Response parameter p2, defined per case. Must be 0 <= p2 <= 1. |

`data` |
a data frame containing the variables named in |

`na.action` |
a function that indicates what should happen when the data contain NAs.
The default action ( |

`...` |
