dimVar was
automatically generated from the remaining columns.SuppressDominantCells() and the underlying function
MagnitudeRule() have been improved:
contributorVar (charVar) can now be
combined with sWeightVar.protectZeros. See this parameter’s
documentation in ?MagnitudeRule.removeCodesFraction allows adjustment of
the effect of the removeCodes parameter.apply_abs_directly determines how
negative values are treated in the rules:
apply_abs_directly = FALSE (default), absolute
values are taken after summing contributions, as performed by
max_contribution() in the SSBtools
package.apply_abs_directly = TRUE, absolute values are
computed directly on the input values, prior to any summation [beyond
preAggregate]. This corresponds to the old behavior of the
function.allDominance = TRUE:
primary.2:80

max_contribution() from SSBtools.tibble and data.table
input (parameter data).
as.data.frame() where necessary to ensure consistent
behavior.preAggregate is TRUE and
aggregatePackage is "data.table", the use of
as.data.frame() is skipped to avoid unnecessary
back-and-forth conversion of data.table objects, preserving
efficiency.GaussSuppressionFromData() and its
wrappers.SSBtools functions FormulaSelection()
and its identical wrapper formula_selection() are now
re-exported.
library(SSBtools) is no longer
necessary to access them.Output from functions like get_klass() in the klassR package or
hier_create() in the sdcHierarchies
package can now be used directly as input. Example of usage:
a <- get_klass(classification = "24")
b <- hier_create(root = "Total", nodes = LETTERS[1:5])
mydata <- data.frame(tree = sample(a$code[nchar(a$code) > 1], 200, replace = TRUE),
letter = LETTERS[1:5])
SuppressSmallCounts(mydata, maxN = 3, hierarchies = list(tree = a, letter = b)) New possibilities for working with both formulas and hierarchies
are now available through the map_hierarchies_to_data()
function.
Improved functionality for combining formulas with the

avoidHierarchical = TRUE, thanks to the new
total_collapse() function which can be applied to

SuppressFewContributors/NContributorsRule introduced in
version 0.8.0. When a single numVar was used as input, the
remove0 functionality failed.SuppressDominantCells() is now considered a common
function for both the nk-dominance rule and the p-percent rule.
pPercent parameter is now exposed in the
SuppressDominantCells() documentation.n parameter in SuppressDominantCells()
now defaults to 1:length(k).

be noted that with this setting, the computational load of the

doubling of the execution time as well. During these computations, “:::”
