`op` |
The algebraic operation to be carried out. |

`eps` |
Criterion for checking equality of two arrays. |

`tab, tab1, tab2, ...` |
Arrays with named dimnames (we call them 'named arrays'). |

`aux` |
Either a list with names and dimnames or a named array from which such a list can be extracted. |

`type` |
If 0 then entries are duplicated. If 3 then averages are computed. If 2 then 0 slices are inserted. |

`lst` |
List of arrays. |

`perm, marg` |
A vector of indices or dimnames or a right hand sided formula giving the desired permutation/margin. |
