I provide this summary because I am repeatedly asked how to install ASReml for use with R. Please also read the installation instructions that are provided by VSNI. Generally, everything is explained, and there is no need to contact the VSNI support.
I am writing these notes mostly from memory, and would be happy if you let me know if there are mistakes/inconsistencies.
ASReml, as used from R, comes in two pieces. First, there is the stand-alone software ASReml that needs to be installed and licensed. Then, there is a separate R package (ASReml-R) that provides the interface glue to drive the ASReml functions from R. You generally need to install both unless you want to work from the relatively primitive command interface provided by ASReml (not ASReml-R). This is recommended for very large data sets that R cannot handle.
With our licensing model, only a limited number of people can use ASReml simultaneously.
To play fair, please:
If you need to allow for negative variance components in your models, or just want nicely formatted output with Wald tests with denominator degrees of freedom, stars indicating significances, variance components, and (if available) stratum variances, then you might want to consider the test.asreml and asreml.nvc functions in my R package (http://www.ieu.uzh.ch/staff/leaders/niklaus/Rstuff.html).
