## Simulated data for illustrating genetic map construction

### Description

Simulated data for an F2 intercross, obtained using `sim.cross`, useful for illustrating the process of constructing a genetic map.

### Usage

    data(mapthis)

### Format

An object of class `cross`. See `read.cross` for details.

### Details

These are simulated data, consisting of 300 F2 individuals typed at 100 markers on five chromosomes. There are no real phenotypes, just a set of individual identifiers. The data were simulated for the purpose of illustrating the process of constructing a genetic map. The markers are all assigned to a single chromosome and in a random order, and there are a number of problematic markers and individuals.

See http://www.rqtl.org/tutorials/geneticmaps.pdf for a tutorial on how to construct a genetic map with these data.
