About ASReml-R

ASReml-R 4.2 is a statistical package that fits linear mixed models using Residual Maximum Likelihood (REML) in the R environment.

For more information about ASReml-R and to obtain a license to use it, we invite you to visit our Webpage.

After installing the package in R, you will be able to load it and activate the license using the following code:
