to countVars even though not explicitely specified.perturbTable() gained an optional new argument
by. In this argument one can use a variable that must also
be listed in countVars. This variable is then used to
compute the magnitute tables by the given 0/1 binary variable.
For an example see ?perturbTable.countVars in
perturbTable() which allows to additionally tabulate any
number or 0/1 variables. For such variables. In such case, the
record-keys of non-contribution units are set to 0 prior to the lookup
in the perturbation tableresults() and replaced it with new
methods ck_freq_table() and ck_cont_table()

argumentspTable) can now be
specified in two different formats. The (default) way is to specify it
as described in the original ABS-paper Methodology for the Automatic
Confidentialisation of Statistical Outputs from Remote Servers at the
Australian Bureau of Statistics (Thompson, Broadfoot, Elazar). An
alternative way is to provide the perturbation tables for count tables
in the “destatis”-format.
ck_create_pTable(type="destatis") returns an exemplary
pTable in this format. In the future, such pTables will likely be
generated from another package. As the requirements regarding record
keys are different in the following lookup-approach, we have already
implemented some (basic) checks for validity of record keys when they
are already available in the microdata used in
ck_create_input().
