DT_legendre: Simulated data for random regression

In sommer: Solving Mixed Model Equations in R

Simulated data for random regression

Description

A data frame with 4 columns; SUBJECT, X, Xf and Y to show how to use the Legendre polynomials in the mmer function using a numeric variable X and a response variable Y.

Usage

data("DT_legendre")

Format

The format is: chr "DT_legendre"

Source

This data was simulated for fruit breeding applications.
