In SSBtools: Statistics Norway's Miscellaneous Tools

The ModelMatrix() function and related functionality for hierarchical computations have now been documented in a paper in The R Journal.
The package description has been updated with this reference (Langsrud, 2023).
Now, remove_empty is an explicit parameter to model_aggregate().
Previously, this had to be done via the mm_args parameter. Old code works as before.
Some tools for formula manipulation are included.
See ?formula_utils
Minor change in Extend0() to allow even more advanced possibilities by varGroups-attribute.
Fix for a rare problem in GaussSuppression(),
Could happen with parallel eliminations combined with integer overflow. Then warning message: longer object length is not a multiple of shorter object length
Minor change to the singleton method "anySum" in GaussSuppression() to align with best theory.
In practice, this rarely makes a difference.
The previous behavior can be ensured by setting singletonMethod to either "anySumOld" or "anySumNOTprimaryOld".
Fixed a zero-weight issue in quantile_weighted().
Now, quantile_weighted(x=c(0,2,0), weights = c(1,1,0)) correctly outputs the 50% value as 1.
A function for checking function inputs has been included and can be used as either CheckInput() or check_input().
The function was originally created in 2016 and has been included in internal packages at Statistics Norway (SSB). Due to its widespread use, it was beneficial to include it in this CRAN package.
