7 Release Notes

7.1 PUBLIC Version of IQR Tools

The versioned versions that are listed below are used internally at IntiQuan. From time to time a public version of IQR Tools is released and made available for download and installation. For information on how to install it, have a look in the installation section further up this book. The source code of the latest public IQR Tools release is always available here: https://iqrtools.intiquan.com/rrepo/src/contrib/IQRtools_99.0.0.tar.gz

7.2 V2025.05 May, 2025

  • Minor fixes
    • NONMEM conversion used in certain places an unsupported ELSEIF. This was updated to not require the use of ELSEIF.
    • Added additional error messages related to the definition of the dosing and modelSpec arguments of IQRnlmeEst.
    • Added additional error message in VPC in case that regression parameters have different values at same time point in dataset.
    • parseNONMEMresults() could return negative RSEs in special cases. These have been changed to positive ones.
    • IQRnlmeData: added check that defined cov and cat and regressor columns do not contain NA values
    • Fixed order of paths when reordering models in compareModels_IQRnlmeProjectMulti()
    • Added feature to IQReventTable targeted at ER simulations with algebraic models in IQRtools (d/dt(dummy)=0 approach): Time varying regressors are kept constant from the time they are set until the time they are changed. If the time at which they change (Tx) is part of the output times at which the user requests a simulation result, then the result is usually the result related to the regressor values in the simulation interval prior to the change (prior to Tx). Then at Tx the new values are set and simulation resumes. This is the correct behavior in most simulation cases of dynamic systems. However, there can be a case where this bevahior needs to be changed. In algebraic models - which happen here mainly in the case of ODE independent exposure-response models it is more correct to calculate output values for changes of repressor parameters already at the exact time of change (Tx). The latter can be accomplished by setting FLAG_ER=TRUE, while the default behavior, as explained above is chosen by FLAG_ER=FALSE. The way how FLAG_ER=TRUE works is that in the case of time dependent regressors, the TIME column of the event table is shifted by a tiny amount (1e-15 time units) to the left for all TIME entries following the first one.

7.3 V2025.03 March, 2025

  • Update to CRAN snapshot https://cran.intiquan.com/snapshot/2025-04-22/
  • Minor fixes
    • Fixed an issue in the previous version that did not generate correctly the covariate forestplots when more than one covariate was present on a parameter.
    • plotETACOV_IQRnlmeProject provided log(COV) plots only for covaiates that strictly had >0 values. This was changed. The linear plot is done normally, for the log plot the data points with COV<=0 are removed and the number of removed points is reported in the subtitle to the figure.
    • IQRnlmeProject provides better support when for NONMEM a CMT column is required.
