\title{Print Summary of Record Linkage Data}
\description{Prints information on \code{\link{RecLinkData}} and
\code{"\linkS4class{RecLinkResult}"} objects.}
\usage{
\method{summary}{RecLinkData}(object,...)
\method{summary}{RecLinkResult}(object,...)
#\method{summary}{RLBigDataDedup}(object,...)
#\method{summary}{RLBigDataLinkage}(object,...)
}
\arguments{
\item{object}{The object for which to print a summary.}
\item{...}{Additional arguments from the generic, silently ignored.}
}
\details{
(The following information is probably outdated as of Nov 17, 2011.)
The printed information for \code{\link{RecLinkData}} objects
includes:
\itemize{
\item The number of records.
\item The number of record pairs.
\item The number of true matches, true non-matches and pairs with unknown
status.
\item If weights have been calculated for this object, a textual histogram
of the weight distribution.
}
Information on \code{"\linkS4class{RecLinkResult}"} objects includes all of the
above and the following:
\itemize{
\item The number of detected links, non-links and possible links.
\item 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).
\item A cross-classified table counting true matching status against
classification. The true matching status is represented as logical
values, possibly including \code{NA} for unknown status.
Classification results are represented by:
\describe{
\item{\code{"L"}}{for links,}
\item{\code{"P"}}{for possible links}
\item{\code{"N"}}{for non-links}
}
}
}
\value{Returns an invisible \code{NULL} and is used for its side effect.}
