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