LazyLinkedTables: Linked tables by full 'GaussSuppressionFromData' iterations

In GaussSuppression: Tabular Data Suppression using Gaussian Elimination

Linked tables by full GaussSuppressionFromData iterations

Description

AdditionalSuppression is called several times as in ChainedSuppression

Usage

LazyLinkedTables(..., withinArg = NULL, maxIterLinked = 1000)

Arguments

...	Arguments to GaussSuppressionFromData that are kept constant.
withinArg	A list of named lists. Arguments to GaussSuppressionFromData that are not kept constant.
maxIterLinked	Maximum number of GaussSuppressionFromData calls for each table.

Details

This function is created as a spin-off from AdditionalSuppression and ChainedSuppression. The calculations run GaussSuppressionFromData from the input each time. There is no doubt that this can be done more efficiently.

A consequence of this lazy implementation is that, in output, primary and suppressed are identical.

Note that there is a residual risk when suppression linked tables by iterations.

Value

List of data frames

Note

In this function, the parameters makeForced and forceNotPrimary to AdditionalSuppression are forced to be FALSE.

Examples

z1 <- SSBtoolsData("z1")
z2 <- SSBtoolsData("z2")
z2b <- z2[3:5]  # As in ChainedSuppression example 
names(z2b)[1] <- "region"

# The two region hierarchies as two linked tables
a <- LazyLinkedTables(z2, freqVar = 5, withinArg = list(
       list(dimVar = c(1, 2, 4)), 
       list(dimVar = c(1, 3, 4))))

# As 'f' and 'e' in ChainedSuppression example. 
# 'A' 'annet'/'arbeid' suppressed in b[[1]], since suppressed in b[[3]].
b <- LazyLinkedTables(withinArg = list(
       list(data = z1, dimVar = 1:2, freqVar = 3, maxN = 5), 
       list(data = z2b, dimVar = 1:2, freqVar = 3, maxN = 5), 
       list(data = z2, dimVar = 1:4, freqVar = 5, maxN = 1)))
