sdcTable 0.32.7

  • Additional check for createArgusInput() to make sure that the holding variable is integer (if specified)
  • Additional check for colons in labels in createArgusInput()
  • Fix non-default Totals whe using createArgusInput()

sdcTable 0.32.6

  • Improvements in SIMPLEHEURISTIC when adding additional suppressions
  • Add RegSDC as suggested package in order to avoid a CRAN note
  • Skip Unit-Tests for CRAN only

sdcTable 0.32.5

  • Fix singleton-detection procedure in case of existing "dummy-cells" (code "w")

sdcTable 0.32.4

  • Update dependency on Matrix package

sdcTable 0.32.3

  • Make SSBtools::GaussSuppression as method = "GAUSS" available in protectTable()
  • Update of package vignette
  • Small overall fixes
  • Fix creation of tau-Argus batchfiles (typ = "microdata") in case aggregate codes are available in raw input data

sdcTable 0.32.2

  • when applying dominance rules, empty cells (with frequency 0) are never marked primary sensitive
  • do not overwrite pre-existing sensitive cells when applying a threshold rule after a dominance rule with allowZeros = FALSE
  • when computing dominance rules using sampling weights it is ensured that weights are consistently rounded

sdcTable 0.32.1

  • allow invocation of exact previous implementation of "SIMPLEHEURISTIC using method = "SIMPLEHEURISTIC_OLD" in protectTable()
  • fix for edge-cases in "SIMPLEHEURISTIC": weights are temporarily changed for "z"-cells if no additional suppression can be detected
  • combined existing functionality to compute constraint-matrix of a problem instance into (much faster) create_m_matrix()
    • replaced internal methods/functions c_gen_mat_m() and .gen_constraint_matrix() and genMatMFull()
  • re-parametrized internal method c_make_att_prob

sdcTable 0.32.0

  • rewrite of the "SIMPLEHEURISTIC approach
    • is based on (full) constraint matrix written using rcpp
    • rewritten the singleton-detection procedure with rcpp
    • by default attacker-problems are checked (in a loop) for primary sensitive cells and additional supps are added until all required cells are secure (fixes also issue #136, thx Øyvind Langsrud for reporting)
    • the previous (possible unsafe but faster) implemented method can be toggled using parameter solve_attackerprobs in protectTable and protectLinkedTable
  • bugfix in internal method c_gen_mat_m with problems that have a single dimension
  • dominance rules:
    • bugfix when computing rules on weighted data
    • allow nk-dominance rules with n=1 (thx @MaximeBeaute for reporting)
    • increased performance as contributing-units to cells are computed only once
  • improved function attack()
    • problem-formulation and solution using the glpkAPI-package
    • can be used to attack all (suppressed) or specific cells
    • can also be used after computing a solution for the cell suppression problem
  • performance improvements
    • c_quick_suppression() and attack() compute linear deps (.gen_contraint_matrix) only once
    • improvements in computation of contributing units to a cell (contributing_indices)
  • new/updated functions/methods:
    • new function protect_linked_tables()
      • will replace protectLinkedTables() in the future (currently calls new function internally)
      • only allows the SIMPLEHEURISTIC algorithm
    • cell_info() replaces cellInfo() (defunct)
    • change_cellstatus() replaces changeCellStatus() (defunct)
    • new function createRegSDCInput() allows to compute input for e.g RegSDC::SuppressDec
    • removed S4-class definition safeObj and related methods
      • results are stored within sdcProblem-objects (in slot results)
      • rewritten getInfo() using an internal helper-function get_safeobj()
    • new function contributing_indices()
      • returns contributing units (from raw input data) to a cell
      • removed internal helper-function c_contributing_indices()
    • replaced internal S4-method c_cellID with utility-function cell_id()
  • improved examples, documentation, test-data and unit-tests
    • improved and updated documentation getInfo() and setInfo()
    • replaced microData1.RData and microData2.RData
      • generation is reproducible in data-raw
      • data can be loaded using data(microdata1) and data(microdata2)
    • replaced problem.RData and problemWithSupps.RData with sdc_testproblem()
    • better document sdc-code z in primarySuppression()
    • improved and updated vignette (thx to @Krisselack for reporting)

sdcTable 0.31

  • remove debugging output
  • fixing typos in vignettes
  • bugfix in protectLinkedTables()
  • remove dependency on package lpSolveAPI
  • update singleton-detection procedure by allowing to input a threshold value that must be respected for all simple table rows
  • check dominance rules (unweighted variables are used)

sdcTable 0.30

  • various fixes and improvements in createJJFormat()
  • ignore sampling weights in case the input in makeProblem() is a complete table and not microdata
  • sdcProb2df(): if numeric variables are shown; display their weighted values (in case) sampling weights have been specified in makeProblem

sdcTable 0.29

  • change in primarySuppression(): for dominance rule it is now only possible to specify underlying variables by name (using argument numVarName) and no longer by index to avoid errors
  • fixes in primary suppression for dominance rules
  • create files from examples in tempdir()

sdcTable 0.28

  • new function contributing_indices()
