getASRemlVersionLoaded

The number of characters in the asreml version to get.

nchar

A <code><a rd-options="" href="/link/logical?package=asremlPlus&version=4.2-26" data-mini-rdoc="asremlPlus::logical">logical</a></code> indicating whether a fault is to occur 
 if <code>asreml</code> is not loaded.

notloaded.fault

Checks that <code>asreml</code> is loaded and, if it is, returns the first <code>nchar</code> characters of the version that is loaded.

asreml

Assists in automating the selection of terms to include in mixed models when
'asreml' is used to fit the models. Also used to display, in tables and graphs, predictions
obtained using any model fitting function and to explore differences between predictions.
The content falls into the following natural groupings: (i) Data, (ii) Object
manipulation functions, (iii) Model modification functions, (iv) Model testing functions,
(v) Model diagnostics functions, (vi) Prediction production and presentation functions,
(vii) Response transformation functions, and (viii) Miscellaneous functions (for further
details see 'asremlPlus-package' in help). A history of
the fitting of a sequence of models is kept in a data frame. Procedures are available for
choosing models that conform to the hierarchy or marginality principle and for displaying
predictions for significant terms in tables and graphs. The 'asreml' package provides a
computationally efficient algorithm for fitting mixed models using Residual Maximum
Likelihood. It is a commercial package that can be purchased from
'VSNi' <https://www.vsni.co.uk/> as 'asreml-R', who will supply a zip file for local
installation/updating (see <https://asreml.org/>). It is not needed for functions that are
methods for 'alldiffs' and 'data.frame' objects. The package 'asremPlus' can also be
installed from <http://chris.brien.name/rpackages/>.
