GaussSuppression (version 0.9.2)

GaussSuppressDec: Cell suppression with synthetic decimal numbers

Description

GaussSuppressionFromData is run and decimal numbers are added to output by a modified (for sparse matrix efficiency) version of SuppressDec.

Usage

GaussSuppressDec(
  data,
  ...,
  output = NULL,
  digits = 9,
  nRep = NULL,
  rmse = pi/3,
  sparseLimit = 500,
  rndSeed = 123,
  runIpf = FALSE,
  eps = 0.01,
  iter = 100,
  mismatchWarning = TRUE,
  whenDuplicatedInner = NULL,
  whenMixedDuplicatedInner = warning
)

Value

A data frame where inner cells and cells to be published are combined or output according to parameter output.

Arguments

data

Input daata as a data frame

...

Further parameters to GaussSuppressionFromData

output

NULL (default), "publish", "inner", "publish_inner", or "publish_inner_x" (x also).

digits

Parameter to RoundWhole. Values close to whole numbers will be rounded.

nRep

NULL or an integer. When >1, several decimal numbers will be generated.

rmse

Desired root mean square error of decimal numbers. Variability around the expected, according to the linear model, inner frequencies. The expected frequencies are calculated from the non-suppressed publishable frequencies.

sparseLimit

Limit for the number of rows of a reduced x-matrix within the algorithm. When exceeded, a new sparse algorithm is used.

rndSeed

If non-NULL, a random generator seed to be used locally within the function without affecting the random value stream in R.

runIpf

When TRUE, additional frequencies are generated by iterative proportional fitting using Mipf.

eps

Parameter to Mipf.

iter

Parameter to Mipf.

mismatchWarning

Whether to produce the warning "Mismatch between whole numbers and suppression", when relevant. When nRep>1, all replicates must satisfy the whole number requirement for non-suppressed cells. When mismatchWarning is integer (>0), this will be used as parameter digits to RoundWhole when doing mismatch checking (can be quite low when nRep>1).

whenDuplicatedInner

Function to be called when default output and when cells marked as inner correspond to several input cells (aggregated) since they correspond to published cells.

whenMixedDuplicatedInner

Function to be called in the case above when some inner cells correspond to published cells (aggregated) and some not (not aggregated).
