\title{Print summary of a genetic map}
\description{
Print summary information about a \code{map} object.
}
\usage{
\method{summary}{map}(object, \dots)
}
\arguments{
\item{object}{An object of class \code{map}, which is a list of
vectors (or, for a sex-specific map, 2-row matrices), each specifying
the locations of the markers. The object can also be of class
\code{cross}, in which case the function \code{\link[qtl]{pull.map}}
is used to extract the genetic map from the object.}
\item{\dots}{Ignored at this point.}
}
\value{
An object of class \code{summary.map}, which is just a data.frame
containing the number of markers, length, the average inter-marker
spacing, and the maximum distance between markers, for each chromosome
and overall. An attribute \code{sexsp} indicates whether the map was
sex-specific.
