map2table {qtl} | R Documentation

## Convert genetic map from list to table.

### Description

Convert a map object (as a list) to a table (as a data frame).

### Usage

    map2table(map, chr)

### Arguments

`map` | A `map` object: a list whose components (corresponding to chromosomes) are either vectors of marker positions or matrices with two rows of sex-specific marker positions.
`chr` | Optional vector indicating the chromosomes to consider. This should be a vector of character strings referring to chromosomes by name; numeric values are converted to strings. Refer to chromosomes with a preceding `-` to have all chromosomes but those considered. A logical (TRUE/FALSE) vector may also be used.

### Value

A data frame with two or three columns: chromosome and sex-averaged position, or chromosome, female position, and male position.

The row names are the marker names.
