MagmaClustR (development version)

MagmaClustR 1.1.0

CRAN release: 2022-11-01

Major

  • Provide 4 vignettes explaining in detail how the different features of MagmaClustR work on practical examples.
  • Implement expand_grid_inputs() to help create customised n-dimensional input grids on which to evaluate the GP.
  • Implement regularize_data() to project a dataset on a specific input grid, (possibly to control the size of the resulting covariance matrices and the associated running time).
  • Add an internal ‘Reference’ column to datasets, to provide an adequate identifier for multidimensional inputs.
  • Implement a new version of simu_db() to generate more realistic 2-D datasets.

Minor

  • Round inputs to 6 significant digits to avoid numerical errors.
  • Generalise the creation of a grid in any dimension when ‘grid_inputs’ is not specified in the prediction functions.

MagmaClustR 1.0.1

CRAN release: 2022-08-29

Major

Remove the package ‘optimr’ dependency and switch to base ‘optim()’ function Increase convergence tolerance in ‘optim()’, which was too slow

Minor

Fix the warnings about the absolute value function in the Cpp code Remove error message in ‘train_magmaclust()’ when common_hp_k = FALSE Change the default intervals for hyper-parameters in ‘simu_db()’ Automatically remove rows with missing data Change position of the ‘grid_inputs’ argument in prediction functions Remove the internal functions from the index documentation *Fix ‘ID’ in hyperposterior() and hyperposterior_clust() when not character
