Variance Component Example

Description

This corresponds to (a sample of) the dataset presented in Giraud et al. (2017).

Usage

data("VarianceComponentExample")

Format

The format is: List of 3

Data

'data.frame': 432 obs. of 5 variables

Trial

a factor with 2 levels

CodeHybrid

a factor with 177 levels

CodeDent

a factor with 116 levels

CodeFlint

a factor with 122 levels

Trait

a numeric vector

KinshipD

num [1:116,1:116]

KinshipF

num [1:122,1:122]

Details

The list contains three elements:

• Data: a data frame containing the information about hybrids (trials, hybrid names, dent parental lines, flint parental lines and phenotypes)

• KinshipD: a matrix of simple relatedness coefficients between dent lines

• KinshipF: a matrix of simple relatedness coefficients between flint lines
