## Example Cross object from R/QTL with multiple traits

### Description

Cross object from R/QTL, an object of class `cross` from R/QTL. See `read.cross` for details.

### Usage

    data(multitrait)

### Format

Cross object from R/QTL

### Details

Arabidopsis recombinant inbred lines by selfing. There are 162 lines, 24 phenotypes, and 117 markers on 5 chromosomes.

### Source

Part of the Arabidopsis RIL selfing experiment with Landsberg erecta (Ler) and Cape Verde Islands (Cvi) with 162 individuals scored (with errors at) 117 markers. Dataset obtained from GBIC - Groningen BioInformatics Centre
