v0.17

Major parts of the package were rewritten in this version. The following main changes are now described:

• Definition of hierarchies
  It is now required to directly use functionality from sdcHierarchies to setup hierarchies when defining of tables. The following changes are possibly required in existing code.

  • replace ck_create_node() with hier_create()
  • replace ck_add_nodes() with hier_add()
  • replace ck_delete_nodes() with hier_delete()
  • replace ck_rename_nodes() with hier_rename()

• Removing "abs"-input format
  For the sake of simplification, the differentiation between the "abs" and "destatis" format was removed. Internally, only the "destatis" format is used.

• Removing possibility to perturb magnitude tables
  The feature to perturb continuously scaled variables (magnitude tables) was removed in version 0.17 of the package as the input format for perturbation tables is not yet finalized. Future versions of the package will gain the functionality to perturb magnitude tables again.

• Simplification
  In order to simplify the application of the package, the process of defining, modifying and perturbing tables was modified. The implementation in versions >=0.17 is based on R6 classes and is described in detail in the new and package vignette that can be viewed after installation of the package using ck_vignette() or online.

no pThreshold

• removed placeholder for pThreshold in perturbTable()

sdcHierarchies_4_all

• make use of new package sdcHierarchies to generate and update hierarchies
• new function ck_rename_nodes()
• perturbTable() got a new argument pThreshold that allows to specify a threshold above no perturbation is applied independent from the perturbation table.

Prototype for Testing

This is the prototype-version of cellKey for testing purposes
