## Print Summary of Record Linkage Data

### Description

Prints information on `RecLinkData` and `"RecLinkResult"` objects.

### Usage

    ## S3 method for class 'RecLinkData'
    summary(object,...)

    ## S3 method for class 'RecLinkResult'
    summary(object,...)

### Arguments

`object` | The object for which to print a summary.
`...` | Additional arguments from the generic, silently ignored.

### Details

The printed information for `RecLinkData` objects includes:

- The number of records.

- The number of record pairs.

- The number of true matches, true non-matches and pairs with unknown status.

- If weights have been calculated for this object, a textual histogram of the weight distribution.

Information on `"RecLinkResult"` objects includes all of the above and the following:

- The number of detected links, non-links and possible links.

- The following error measures, if the true matching status of all record pairs is known: Alpha error (ratio of false links to matches), beta error (ratio of false non-links to non-matches) and accuracy (ratio of correctly classified pairs to the total number of pairs).

- A cross-classified table counting true matching status against classification. The true matching status is represented as logical values, possibly including `NA` for unknown status. Classification results are represented by:

  `"L"`

    for links,

  `"P"`

    for possible links

  `"N"`

    for non-links

### Value

Returns an invisible `NULL` and is used for its side effect.
