Main functionality changes

  • Argument extend added to the update method enabling to perform hyperparameter re-estimation, using the previous hyperparameter values stored in the model as starting points for the new optimization.

Minor display changes

  • Line type of the mean function in plotSims.fgpm changed to dashed (lty = 2) for easier inspection.

  • The trace, pbars and control.optim arguments were added to update.fgpm for a wider control of displays.

  • Convergence code and negated log-likelihood value added as slots of fgpm objects to make them more informative.

  • Forwarding of optim() control argument enabled in fgpm through control.optim.

  • Following the addition of control.optim, we improved the functionality of the fgpm and fgpm_factory arguments to control the display of funGp native progress messages

  • The trace, pbars and control.optim arguments were added to modelDef for a wider control of displays.

  • Pre-existent future backend registers protected as suggested by the author of future in issue #14

  • Pre-existent foreach adapters registers protected as suggested by the author of future in issue #15

Main functionality corrections

  • The summary method has been added for Xfgpm and fgpm objects.

  • New classes "predict.Xfgpm" and "simulate.Xfgpm".

  • All plotters are now plot methods for the classes "Xfgpm", "fgpm", "predict.Xfgpm" or "simulate.Xfgpm".

  • New functions modelDef and [[ to refit a fgpm object from a Xfgpm one.

Main flow changes

  • format4pred() removed and replaced by get_active_in() as anticipated in 0.2.0 release.

Minor flow changes

  • Own rm_between() function implemented to remove dependency on the qdapRegex package.

  • Minor change to resolve a %dopar% issue during parallelized processes based on %dorng%.

Minor flow changes

  • Minor change to resolve a check issue evoked by CRAN.

Minor flow changes

  • Minor change to resolve a check NOTE related to the declaration in Imports of the plyr package.

Main functionality corrections

  • Fixed incoherence between the sorting order of the list of explored models and their performance statistic, stored at the xm@log.success@sols and xm@log.success@fitness slots of the Xfgpm object delivered by fgpm_factory(). Now the models in xm@log.success@sols are correctly sorted in decreasing order by performance.

  • Resolved bug causing crash in fgpm_factory() during structural optimization with only functional inputs, e.g., for the call fgpm_factory(fIn = fIn, sOut = sOut). Thanks to Jérémy Rohmer for pointing out the bug.

  • Resolved bug causing crash in fgpm_factory() during structural optimization with only scalar inputs, e.g., for the call fgpm_factory(sIn = sIn, sOut = sOut).

Minor display changes

  • Improved display of progress bars for fgpm() and fgpm_factory().

  • Improved placing of the legend in plotX() to prevent hiding important information.

Minor flow changes

  • This is the first release of funGp.
