## Print summary of a genetic map

### Description

### Usage

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

### Arguments

`object` | An object of class `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 `cross`, in which case the function `pull.map` is used to extract the genetic map from the object.
`...` | Ignored at this point.

### Value

An object of class `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 `sexsp` indicates whether the map was sex-specific.
