### asremlPlus Version 4.4.40 (2024-10-27

Fix issue with building for CRAN.

### asremlPlus Version 4.4.39 (2024-10-26

Fixed a bug in pickLSDstatistic that occurs when there is only one prediction for a level of a

`factor.combination`

specified using the argument`LSDby`

.Fix a bug that meant that the settings of the arguments

`allow.unconverged`

,`allow.fixedcorrelation`

and`update`

for addSpatialModel.asrtests, addSpatialModelOnIC.asrtests and chooseSpatialModelOnIC.asrtests were not being passed on to functions that they called. Set the defaults for the arguments`allow.unconverged`

,`allow.fixedcorrelation`

and`update`

to`TRUE`

for addSpatialModel.asrtests, addSpatialModelOnIC.asrtests and chooseSpatialModelOnIC.asrtests to match the defaults that had in practice been the settings of these arguments for the functions that fit the spatial models.Fix bug in fitting correlations models in addSpatialModel.asrtests, addSpatialModelOnIC.asrtests and chooseSpatialModelOnIC.asrtests where correlations on both grid dimensions become bound.

Add code to remove a correlation function from a term when one of more of its correlation parameters are bound and the argument

`allow.fixedcorrelation`

is`FALSE`

in fitting the function using addSpatialModel.asrtests, addSpatialModelOnIC.asrtests and chooseSpatialModelOnIC.asrtests.Add checks and fixes for ill-fitting correlations models in addSpatialModel.asrtests, addSpatialModelOnIC.asrtests and chooseSpatialModelOnIC.asrtests, such as for when (i) bound residual term after fitting a correlation term, (ii) all random and residual terms in one dimesion are bound, and (iii) some correlations on both grid dimensions become bound.

### asremlPlus Version 4.4.38 (2024-08-19

Add check that spatial variance is not bound whilst the nugget variance is positive when fitting correlation models in addSpatialModel.asrtests, addSpatialModelOnIC.asrtests and chooseSpatialModelOnIC.asrtests. If it is, fix the nugget variance.

Add the argument

`nugget.variance`

to addSpatialModel.asrtests, addSpatialModelOnIC.asrtests and chooseSpatialModelOnIC.asrtests to control the fitting of a nuggetvariance when fitting correlation models.Add

`trace`

argument addSpatialModel.asrtests, addSpatialModelOnIC.asrtests and chooseSpatialModelOnIC.asrtests, primarily for tracking the fitting of correlation models.Add traps for errors resulting from singular information matrices when fitting correlation models in addSpatialModel.asrtests, addSpatialModelOnIC.asrtests and chooseSpatialModelOnIC.asrtests.

Fix bug in addSpatialModel.asrtests, addSpatialModelOnIC.asrtests and chooseSpatialModelOnIC.asrtests when fitting metric correlation functions.

Fix bug in newfit.asreml that occurred when change to random model results in no random terms.

### asremlPlus Version 4.4.37 (2024-07-23

Modify the fitting of corb correlation models in addSpatialModel.asrtests, addSpatialModelOnIC.asrtests and chooseSpatialModelOnIC.asrtests to make it more robust.

Fix a bug in infoCriteria.asreml and infoCriteria.list that caused an

`incorrect-dimensions`

error when computing the full likelihood.

### asremlPlus Version 4.4.36 (2024-07-01

Make sure that, when

`false.pos.wt`

is used with pickLSDstatistics and there are several values with the same weighted sum, LSDstatisics with less false positives are favoured.

### asremlPlus Version 4.4.35 (2024-06-19

Fix faulty links in manual.

### asremlPlus Version 4.4.34 (2024-06-19

Add

`EGLS.linTransform`

to linTranform.alldiffs, predictPlus.asreml, predictPresent.asreml and pairdiffsTransform.alldiffs.Add S3 method function isCompoundSymmetric.matrix.

`wald.tab`

component of an`asrtests.obj`

.

### asremlPlus Version 4.4.30 (2024-03-03

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.

### asremlPlus Version 4.4.29 (2024-02-26

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`

.

### asremlPlus Version 4.4.28 (2024-02-13

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.

### asremlPlus Version 4.4.27 (2024-02-05

Spell check the manual.

Revise the detection of variance parameters involving

`sections`

in addSpatialModel.asrtests, addSpatialModelOnIC.asrtests and chooseSpatialModelOnIC.asrtests.

### asremlPlus Version 4.4.26 (2024-02-01

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.

### asremlPlus Version 4.4.25 (2024-01-15

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.

### asremlPlus Version 4.4.24 (2023-12-20

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.

### asremlPlus Version 4.4.23 (2023-12-12

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.

### asremlPlus Version 4.4.22 (2023-11-14

Add the S3-method function convEffectNames2DataFrame.asreml.

### asremlPlus Version 4.4.21 (2023-11-05

Increment version for resubmission to CRAN after fixing an S3 method declaration error.

### asremlPlus Version 4.4.20 (2023-11-05

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.

### asremlPlus Version 4.4.19 (2023-10-30

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.

### asremlPlus Version 4.4.18 (2023-10-29

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`

.

### asremlPlus Version 4.4.17 (2023-10-26

Fix bug in investigating nugget variance for correlation models when there are

`sections`

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.

### asremlPlus Version 4.4.16 (2023-10-18

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.

### asremlPlus Version 4.4.15 (2023-10-02

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.

### asremlPlus Version 4.4.14 (2023-08-28)

Minor internal code changes.

### asremlPlus Version 4.4.13 (2023-08-24)

`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"`

.

### asremlPlus Version 4.4.12 (2023-08-03)

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.

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.Fix problem detected during CRAN submission that found setvarianceterms.asreml was apparently an unregistered exported generic.

Fix bug in false.pos and false.neg for

`LSDtype`

set to`supplied`

when`LSDby`

is not`NULL`

.Add quantiles 25 (

`q25`

) and 75 (`q75`

) to the values that`LSDstatistic`

can take and the exploreLSDs.alldiffs investigates.Allow for multiple

`LSDstatistic`

values when`LSDtype`

### asremlPlus Version 4.3-24 (2021-10-14)

Make sure that when

`predicted.values`

and the associated`vcov`

and`sed`

### asremlPlus Version 4.3-11 (2021-07-28)

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.

### asremlPlus Version 4.3-10 (2021-07-5)

and with dealing with unconverged models.

### asremlPlus Version 4.2-10 (2020-02-07)

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`list`

s 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

`formula`

e 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.
