Run the following code to install and licence ASReml-R:


Then paste your licence code at the prompt.

Note: Licencing ASReml-R

ASReml-R is a proprietary R package which is sold and supported by VSN International, and requires a licence code to activate and run. This licence code is checked for validity via the internet, and may require opening some network ports on your computer to successfully activate. Further information about the licence requirements can be obtained from VSNi directly.

The developers of biometryassist do not provide support for ASReml-R via way of bug reports or software patches, and any problems with the ASReml-R software should be directed to VSN International. These installation instructions are provided on a best-effort basis and any problems with the steps in this installation guide should be reported to the developers of biometryassist.

Licence key for University of Adelaide Staff and Students

You will receive an email with a licence key if you hold a valid University of Adelaide account.

Package method

The easiest way to install ASReml-R is to use the biometryassist package, which includes an automated install_asreml() function. This function will detect the appropriate version of R and your operating system, and download the matching version of asreml. If you’d rather not install the full package for this one function, you can simply source the function from the public GitHub repository instead, and run the function. See Function Only Method.

The biometryassist package is on CRAN, so can be installed using the regular method:


Once installed, load the package ready for use with:

This package will stay installed between R sessions, but will need to be loaded with the library command any time you want to use the functions within it.

Function Only Method

To use only the function, without the additional overhead of the biometryassist package, source it with the following command:

if(!require(rlang) | !require(curl)) install.packages(c("rlang", "curl"))

This will enable use of the function within the current R session. If you close R, you will need to run the line above again to enable use of the function. Note this requires the packages rlang and curl to be installed, which is accomplished in the first line above if necessary.

Installing ASReml-R

Once the install function is available, simply run it and wait for it to finish:

The following output is typical:

> install_asreml()

Activating ASReml-R

To activate the licence code once asreml is installed, run the following commands (noting the spelling of license):


You will then be prompted to provide a licence code, which is a 16 character alpha-numeric code:

> asreml.license.activate()
Please enter your activation code (RET or 0 to exit): AAA1-BBB2-CCC3-DDD4

A valid licence code will produce the following output:

License activation successful
Licensed to <Orginisation or name> - <reference code(s)>
Ref: <reference code> Expires: <expiry date>, <n> days.

Additional Installation Options

The install_asreml() function has a number of additional arguments, which you can read about on the documentation site.

If you already have ASReml-R installed, and want to update it or reinstall it, you can use the update_asreml() function, or install_asreml(force = TRUE).

install_asreml(force = TRUE) # Equivalent to the above
