Trap errors issued by svd function from base R in computing generalized inverses for R2adj.asreml. Instead, issue a warning and return NA.
Fix a bug in estimateV that meant that terms involving the asreml at function on other than the first variable in the term caused an error.
Instead of producing an error when the number of columns in the design matrix does not equal the number of coefficients for the term, now add columns of zeros for missing design-matrix columns. An error may still occur when this does not work.
Add checks in estimateV.asreml and R2adj.asreml for when the design matrix for a term is not available. Rather than issue an error, NA is returned and an attribute missing.termmatrix added that contains a list of the problematic terms. Also added an error to variofaces.asreml and bootREMLRT for when this problem occurs.
Extend the the include.which.fixed and include.which.random arguments of R2adj.asreml to process correctly formulae to update the existing fixed and random formula using a formula that includes the '.' and terms, typically a list of bracketed terms preceded by a '-' so that terms are removed from a formula.

There has been several changes to the arguments of makeTPPSplineMats.data.frame, addSpatialModel.asrtests, addSpatialModelOnIC.asrtests or chooseSpatialModelOnIC.asrtests as follows:
The default for ngridangles has changed to NULL to provide for using an optimizer to search for the optimal rotation.
The arguments dropRowterm and dropColterm have been replaced with the more general arguments dropFixed and dropRandom.
The default for asreml.option has changed from mbf to grp. While grp requires more storage that mbf, it is easier to apply asreml and asrtests methods to fitted models when grp is used.

Added reporting the optimal rotation angles to the test.summary when rotateX is TRUE. Also, added theta(s) as an attribute to the asreml.object.
Added the which.rotacriterion so that one could choose between the deviance, likelihood, AIC and BIC as the criterion to use in determining the optimal roation angle for rotating the eigenvectors of the penalty matrix.
Add the capacity to parallel process, for each column angle, the search of the row angles. This option is only available for the asreml.option set to grp.
Removed the need to precede a call to these functions with a call makeTPPSplineMats.data.frame when asreml.option is set to mbf.
Fix a bug in fitting natural cubic smoothing spines (TPNCSS) using these functions where only the first of the sections had splines fitted to it.
Change from ordinal numbers to levels in labelling the fitting of correlation corr spatial models when using these functions.
Modify makeTPPSplineMats.data.frame so that the default enviroment of the data.frames for the mbf option of asreml.opt is that of the function that calls makeTPPSplineMats.data.frame. Also, for mbf.env set to NULL, do not assign the mbf data.frames; just include them in the list that is returned.
Make the data.plus component of the list produced by makeTPPSplineMats.data.frame when asreml.option is set to mbf equivalent to that produced when asreml.option is set to grp.
Corrected bug in detecting Fixed (F) variance components in rmboundary.asrtests.

Add code to carry out a grid search to find the optimal angle by which to rotate the eigenvectors of the penalty matric when fitting P-splines. Add arguments rotateX and ngridlines to addSpatialModel.asrtests, addSpatialModelOnIC.asrtests and chooseSpatialModelOnIC.asrtests to allow the use to request that grid seach be made for the optimal ritation angle and to control the size of the grid searched.
Fix a bug in fitting a correlation model that occurs when addSpatialModel is used to fit the model.
There remains an svd bug with the oneMKL libraries version 2023.1.0 that is causing problems for IClikelhood set to "full".
Modifications to deal with classhes between multithreading and external linear algebra packages under Windows. The environmental variable OMP_NUM_THREADS needs to be set to 1 if parallel processing is to be undertaken on a Windows machine. This can be done for individual tasks by using Sys.setenv("OMP_NUM_THREADS" = 1) prior to running the task; otherwise, the environmental variable can be set for all tasks in the Windows system via Advanced system settings > Envirnomental Variables.

The designation of estmates on the boder of the parameter space has changed from fixed (F) to (B) e.g. correlations.
When the levels of a factor are being specified in terms with an at, as opposed to an ordinal number for the position of the level in the levels list, then the levels must be enclosed in single or double quotes. Further, the names of the terms will nclude single or double quotes.

There has been a substantial revision of the calculation and saving of the LSD component of an alldiffs object.
The argument meanLSD.type has been changed to LSDtype. All functions that are S3 methods for alldiffs objects will check for the meanLSD.type attribute and, if found, change it to LSDtype.
The option supplied has been added to the argument LSDtype so that the user can supply LSD values to replace those in the assignedLSD column of the LSD component.
The two new arguments LSDstatistic and LSDaccuracy have been added. The argument LSDstatistic allows a choice of minimum, mean, median or maximum. The values of the nominated LSD statistics are stored in a column of the LSD component named assignedLSD. The argument LSDaccuracy allows the specification of a statistic summarizing the differences between the the LSDs and the assigned LSD value for each row of the LSD component. The values of the chosen measure are stored in a column of the LSD component named accuracyLSD. These two arguments have been added to the functions allDifferences.data.frame, as.alldiffs.object, as.alldiffs, linTransform.alldiffs, pairdiffsTransform, predictPlus.asreml, predictPresent.asreml, ratioTransform.alldiffs, recalcLSD.alldiffs and redoErrorIntervals.alldiffs.
The LSD component is always calculated and stored as a component when pairwise is TRUE.
A new argument accuracy.threshold has been introduced to control the addition of a column names LSDwarning to the predictions of an alldiffs object. THis column indicates whether or not the an halfLeastSignificant error.interval is reliable as determined using the supplied value of accuracy.threshold.
The attributes of an alldiffs object and of the predictions component have been modified. The arguments LSDtype, LSDstatistic and LSDby, if set, are attributes of an alldiffs object. They are also attributes of a prediction.frame and the backtransforms component of an alldiffs object, as is LSDvalues, when halfLeastSignificant error.intervals are specified. The LSDvalues attribute has the values used in calculating half-LSD intervals. The meanLSD attribute has been removed.
A separate entry for LSD.frame has been introduced into the manual to dedscribe the data.frame that is stored in the LSD component of an alldiffs object.

Modify URLs for CRAN submission.
Try to neutralize problem that occurs with colourise in print.predictions.frame.
Rebuild for R 4.0.3 and recompile vignettes for CRAN submission.
Include a key option in the which that produces vparametersummary rather than the full asremlsummary.
Remove attributes from formuale when executing printFormulae.
Add the ChickpeaEnd data set.
Modify code so that error intervals are set to NA when the LSDs are zero.
Modify code for calculating LSDs so that all zero LSDs are allowed; this is needed when a linear transformation has resulted in predictions that are equal.
Rebuild the vignettes prior to CRAN submission.
Add envir argument to getFormulae.asreml and printFormulae.asreml to make them more robust to where the objects in the asreml.obj have been defined.
Fix bug in getFormulae.asreml and printFormulae.asreml that occurs when formula(e) have been supplied to asreml in an object.
Change the Maintainer email address.
Add ellipsis to as.asrtests call within an rmboundary.asrtests call so that arguments in the calling routine are passed through.
Add a trap in recalcWaldTab.asrtests for a NULL wald.tab before dealing with denDF so that recalcWaldTab.asrtests throws a warning rather than an error.
Modify recalcWaldTab.asrtests to deal with a Wald table that has Chi-square instead of F statistics (this happens when denDF = "none".)
Increment version number for resubmission to CRAN.
Fix bug in changeTerms when both addFixed and dropFixed are NULL.
Revisions to the manual.
Fix bug in forming test.summary.
Added the IClikelihood argument to chooseModel.asrtests, reparamSigDevn.asrtests, rmboundary.asrtests, testranfix.asrtests, testresidual.asrtests, and testswapran.asrtests.
Fix bug in printFormulae when the formula is long.
Various bug fixes associated with asreml-R version 3.
Fix bug in processing a formula that includes an at function.
Removed the material.diff argument and the both option from the which.IC argument of changeModelOnIC.
Change likelihood in infoCriteria to IClikelihood to make it consistent with other functions.
Replace tol.diff with material.diff and set the default to 0.5 in changeModelOnIC.
Revise all vignettes.
Add a new vignette for the use of information criteria with the wheat experiment.
Fixed bugs in changeModelOnIC associated with addFixed and dropFixed and with dealing with unconverged models.
This version represents a major revision in that the facilities for employing information criteria (AIC and BIC) have been considerabley expanded. The infoCriteria method has been modified to add the possibility of calculating not only the the information criteria based on the REML likelihood, but those based on the full likelihood instead. There are now two infoCriteria methods, one for asreml objects and the other for lists of asreml objects. An alternative is to use changeTerms.asrtests wiith IClikelihood set to REML or full and the information criteria will be included in the The test.summary of the asrtest object. A new function changeModelOnIC has been included to allow model selection to be based on the information criteria, rather than on hypothesis tests. However, the two methods of selecting models can be interweaved.
Add argument omit.columns to print.test.summary that allows the specification of columns to be omitted from the printout.
Various modifications to the internal code for the handling of the test.summary component of an asrtest.object to allow more flexibility in the make up of test.summary.
Add function iterate.asrtests to execute additional iterations of the fit stored in an asreml.obj within an asrtests object; the model itself cannot be changed.
Add functions getFormulae.asreml and printFormulae.asreml to extract and print the formulae stored in the call of an asreml object.
Add trace argument to newfit.asreml and activated it for asreml-R version 4.
Made R >= 3.5.0 a requirement for asremlPlus.
