Update for CRAN submission.
Revise warning message in R2adj.asreml for when generalized inverse fails.
Add fix for bug in as.asrtests that caused a C stack overflow error when trying to update the wald.tab component of an asrtests.obj.
For chooseSpatialModelOnIC.asrtests, change the abbreviations for the two P-spline models from TPPCS and TPP1LS to TPPSC2 and TPPSL1. If the call to chooseSpatialModelOnIC.asrtests includes the former abbreviations, they will be converted to the new abbreviatons and all output will be labelled with the new abbreviations.
Revise the deocumentation of the P-spline details for addSpatialModel.asrtests, addSpatialModelOnIC.asrtests or chooseSpatialModelOnIC.asrtests.
For R2adj.asreml, correct the check that terms to be included in the random model for calculating R2.adj are in the fitted model so that a warning is no longer issued when a term for inclusion differs from a fitted term only in the order of the factors/variables comprising the terms.
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.
Spell check the manual.
Revise the detection of variance parameters involving sections in addSpatialModel.asrtests, addSpatialModelOnIC.asrtests and chooseSpatialModelOnIC.asrtests.
Implement bespoke strategy for fitting corb correlation models that first fits a random units length term and constrains the residual variance to one. Then, the corb models are fitted and, when corr.orders is set to 0, up to 10 correlation bands are fitted depending on whether additonal bands improve an information criterion.
Fix a bug in estimateV when a corb function is involved in a variance term and asreml version 4.2 is being used.
Minor corrections to documentation for makeTPPSplineMats.data.frame, addSpatialModel.asrtests, addSpatialModelOnIC.asrtests or chooseSpatialModelOnIC.asrtests.
Fixed bugs in passing the arguments for setvarianceterms.call via ... from addSpatialModel.asrtests, addSpatialModelOnIC.asrtests and chooseSpatialModelOnIC.asrtests to changeTerms and changeModelOnIC.asrtests.
Minor revisions to documentation for R2adj.asreml.
Add an error for a NULL vcov component in the alldiffs.obj supplied to the ratioTransform.alldiffs function.
Add printPlot argument to plotPredictions.data.frame and change the function to return the plot.
Add function R2adj.asreml to calculate an adjusted coefficient of determination for linear mixed models.
Fixed bugs in estimateV for asr_str terms with non-diagonal variance structures.
Rectify a problem in extracting the correct columns of the design matrix for some terms that affected estimateV.
Update the vignettes.
Add link to GitHub issues page for BugReports in DESCRIPTION file.
Fix a bug in plotLSDerrors so that the correct errors are now plotted.
Add argument false.pos.wt to pickLSDstatistics.alldiffs, which when it is not NULL results in mininzing the weighted sum of the false.pos and false.neg comparisons of pairwise differences.
Add the use of the R optimizer nloptr::bobyqa to search for the optimal angles for the rotation of the eigenvlues of the penalty matrix when fitting cubic P-splines using addSpatialModel.asrtests, addSpatialModelOnIC.asrtests or chooseSpatialModelOnIC.asrtests. This provides an alternative to searching over a two-dimensional grid of angles.
Fix a bug in the fits used in searching for optimal rotation angles by doing the search before any spatial P-spline models are fitted.
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.
Add the S3-method function convEffectNames2DataFrame.asreml.
Increment version for resubmission to CRAN after fixing an S3 method declaration error.
Revise manual pages to meet cran syntax requirements.
Add the argument usRandLinCoeffs to addSpatialModel.asrtests, addSpatialModelOnIC.asrtests or chooseSpatialModelOnIC.asrtests to control whether to attempt the fit of the unstructured variance model for the constant and linear terms in random interactions with smooth terms. Also, added code to reject the model if any of the variances or covariances are bound.
Fix bug that prevented the fitting of unstructured variance model between the random constant and linear parameters in the interaction of these terms with the random smooth row and random column terms in a TPPCS model.
For fitting in P-spline models using addSpatialModel.asrtests, addSpatialModelOnIC.asrtests or chooseSpatialModelOnIC.asrtests, change the function for fitting the covariance of the constant and the linear term from us to corh or corgh.
Fix bug in investigating nugget variance for correlation models when there are sections.
Further improve the handling of situations in which the residual variance or the spatial variance associated with a correlation term becomes singular or bound in fitting a spatial correlation model using addSpatialModel.asrtests, addSpatialModelOnIC.asrtests and chooseSpatialModelOnIC.asrtests.
Add allow.corrsJointFit argument as a device for dealing with fits that hang when attempting to fit simultaneously both correlations for the two grid dimesnions.
Internal recoding.
Added the maxit option for asreml to addSpatialModel.asrtests, addSpatialModelOnIC.asrtests and chooseSpatialModelOnIC.asrtests, setting its default to 30 for these functions to increase the chances that the models will converge.
Extensively revise the code to improve the handling of situations in which the residual variance or the spatial variance associated with a correlation term becomes singular or bound in fitting a spatial correlation model using addSpatialModel.asrtests, addSpatialModelOnIC.asrtests and chooseSpatialModelOnIC.asrtests.
Revise checking for nugget variance when there are sections and the residual has a separate terms for each section.
Added a basic check for separate random and residual terms for sections and, if there are none, issue a warning that better fitting can result if they are included.
Make the default number of cores (ncores) for parallel processing in bootREMLRT.asreml, simulate.asreml and variofaces.asreml.
Add the function convAsremlobj.asreml that recreates an existing asreml object using the currently loaded asreml version so that the object is compatible with this version.
Made the following modifications to addSpatialModel.asrtests, addSpatialModelOnIC.asrtests and chooseSpatialModelOnIC.asrtests:
Tweaked the code underlying these functions for fitting local spatial variation models to make it more robust.
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.
Added to newfit.asreml, a test for bound and singular terms in a new model when update is TRUE and, if there are any, added code to refit the model as if update was FALSE, to see if any bound terms become unbound terms.
Clarified the dcoumentation of the update argument in all functions that include it.
Minor internal code changes.
Add arguments rotateX and theta to makeTPPSplineMats.data.frame so that the eigenvectors of the penalty matrix used in generating the design matrices for the random terms could be rotated by the angles in theta.
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.

character codes are now stored in both vparameters.type and vparameters.con,
making vpt.char and vpc.char obsolete and so no longer available.
For predict, the intercept-only classify and the name of the column in the
predictions.freame, has changed from (Intercept) to Intercept.
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.

Repurpose row.factor and col.factor arguments of addSpatialModel.asrtests, addSpatialModelOnIC.asrtests and chooseSpatialModelOnIC.asrtests to specify the row and column factors for correlation model where required and add the arguments dropRowterm and dropColterm to specify the main effect terms to be dropped in fitting spline models.
Modified changeTerms.asrtests and changeModelOnIC.asrtests so that the bounds and initial values of terms specified using set.terms without changing any terms in the model.

This bug affected the functions changeTerms.asrtests, changeModelOnIC.asrtests, rmboundary.asrtests, testswapran.asrtests and testranfix.asrtests. In removing a term that involve a single lewvel of a factor in an at function, it is now possible to specify either the level or the level index.

Deprecate the function asrtests, which has been replaced by the function as.asrtests.
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.

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.
