## Quartet concordance factors across Arabidopsis thaliana

### Description

Concordance factors of quartets for 29 A. thaliana accessions and A. lyrata, obtained from chromosome 4 using MDL to delimit loci then BUCKy on each 4-taxon set.

### Usage

    data(quartetCF)

### Format

Data frame with 7 variables and 27,405 rows. Each row corresponds to one 4-taxon set (choosing 4 taxa out of 30 makes 27,405 combinations). The first four variables, named 'taxon1' through 'taxon4', give the names of the 4 taxa in each 4-taxon set. Variables 5 through 7 are named CF12.34, CF13.24 and CF14.23, and give the estimated concordance factors of the 3 quartets on each set of 4 taxa: taxon 1 + taxon 2 versus taxon3 + taxon 4, etc. These concordance factors are the proportion of loci that have a given quartet tree. They were obtained from chromosome 4 using MDL to delimit loci then BUCKy to estimate quartet concordance factors (CFs).
