You need to fit the model on the component scale if you want to use vpredict and the s.e’s. Therefore, you have to be careful with vpredict as ASReml-R does not automatically convert variance ratios to variance components, or their standard errors.

As the variance parameter names can sometimes be long or unwieldy, the variance parameters are represented in vpredict() by the strings “V1”, “V2”,: : : in the order in which they appear in the vparameters component of the ASReml object.īy default for simple models ASReml fits on the ‘gamma’ scale, which means that the returned variance components are variance ratios (For more details please see the ASReml-R Reference Manual Version 4). Vpredict() Compute functions of variance components and their approximate standard errors.įunctions of variance components and their standard errors can be obtained from the vpredict() function.

The Cullis heritability estimator was used.

Some useful aspects of this code are running ASReml analyses within functions, which requires some trickery. As a quick hack you can also include Sys.setenv(ASREML_LICENSE_FILE="/Applications/asreml3/bin") at the beginning of your R script (assuming you put ASReml in this directory).Supplementary note for new function vpredict() in ASReml-R version 4 The objective of the analysis was to explore data, transform as necessary to stabilize residuals, and compare inoculation methods and assays in terms of correlations and heritabilites. If ASReml-R pesters about a missing license, check using "Sys.getenv()" that this environment variable is properly set, and that a valid "asreml.lic" file is really found there.

Asreml r 4 download license#

This file should contain the single line ASREML_LICENSE_FILE='/Applications/asreml3/bin/asreml.lic' (of course this needs to be adapted if you installed ASReml in another directory, or your license file has a different file name). What should work though is to put a file named ".Renviron" in your home directory. There are several options where you can set it in FreeBSD (the Unix underlying MacOS X), including a ".profile" file in your home directory, but it seems not all are considered depending on how R is started from within RStudio. If you have a Mac and it says the license is not found (especially when using RStudio), you have to make sure an environment variable is set that tells ASReml where the license file is located.

From R, use library(asreml) to load the R package providing the interface glue.

This has the advantage that you can use asreml from everywhere, without VPN, as long as you have an internet connection.

I am running the license server outside the university network.

This file needs to be saved in the directory where ASReml resides, or in your home directory. In return, I expect a contribution to the license costs, which will depend on how many people use the license. As of 2018, I have purchased a pool of floating licenses, which means that the total number of simultaneous users is limited, but not the total number of installations.

However, only install the package this way if you know what you are doing. The advantage will be that all users on this computer will have this R package available.

The location where the library is installed may need to be adapted, and you may need superuser rights.

From a terminal, under OS X or Linux, you can also use "R CMD INSTALL -l /usr/lib/R/site-library asreml_3.0_R_", or "R CMD INSTALL asreml_3.0_R_".

Under Windows and newer R versions, you may have to add the option type="binary"

Everything should also work by using install.packages(path_to_your_asreml-R.zip_or_tar.gz_file,repos=NULL) from the R command line.

RStudio), then there generally is an option in the menu to install R packages from a local file. There are several ways in which you can do this:

Install ASReml-R, the R package that is used to interface ASReml from R.

On a Mac, I'd install it in /Applications/asreml3. Under Linux, I usually install it under /usr/local/asreml3, and create a symbolic from /usr/local/asreml3/bin/asreml.sh to /usr/local/bin/asreml.

This software will need to be licensed to run, which is described below. Install ASReml, the stand-alone software.Make sure you have the version that goes with your operating systems (Windows, Mac, Linux 32 or 64bit).

Then, download ASReml and ASReml-R from.

You will need your login credentials later.
