`formula` |
Double right-hand side formula describing covariates of detection and occupancy in that order. |

`data` |
An |

`knownOcc` |
Vector of sites that are known to be occupied. These should be supplied as row numbers of the y matrix, eg, c(3,8) if sites 3 and 8 were known to be occupied a priori. |

`starts` |
Vector of parameter starting values. |

`method` |
Optimization method used by |

`engine` |
Either "C" or "R" to use fast C++ code or native R code during the optimization. |

See `occuPEN`

for details and examples.
