## Computes a (possibly weighted) contingency table

### Description

Computes a contingency table from one or two vectors, with the possibility of specifying weights.

### Usage

```
weighted.table(x, y = NULL, weights = NULL, stat = "freq",
mar = FALSE, na.rm = FALSE, na.value = "NA", digits = 1)
```

### Arguments

`x` |
an object which can be interpreted as factor |

`y` |
an optional object which can be interpreted as factor |

`weights` |
numeric vector of weights. If NULL (default), uniform weights (i.e. all equal to 1) are used. |

`stat` |
character. Whether to compute a contingency table ("freq", default), percentages ("prop"), row percentages ("rprop") or column percentages ("cprop"). |

`mar` |
logical, indicating whether to compute margins. Default is FALSE. |

`na.rm` |
logical, indicating whether NA values should be silently removed before the computation proceeds. If FALSE (default), an additional level is added to the variables (see na.value argument). |

`na.value` |
character. Name of the level for NA category. Default is "NA". Only used if na.rm = FALSE. |

`digits` |
integer indicating the number of decimal places (default is 1) |

### Value

Returns a contingency table.
