localSupp2Wrapper: Local Suppression 2

Description

A wrapper function for function localSupp2 in order to guarantee k-anonymity.

Usage

localSupp2Wrapper(x, keyVars, w, importance=rep(1, length(keyVars)),
method="minimizeSupp", kAnon=2)

Arguments

data frame or matrix

keyVars

column index of key variables

column index of sampling weights

importance

weights for each key variable, see localSupp2()

method

minimizeSupp (default), further methods will be included in future versions of the package

kAnon

parameter for k-anonymity.

Value

Object from class localSupp2.
xAnonresulting data with suppressions
suppsnumber of suppressions in the key variables
totalSuppstotal number of suppressions.
anonymityTRUE, if k-anonymity is achieved
keyVarsindex of the key variables.
importanceweight vector for key variables
kAnonk for k-anoymity

Details

This wrapper function guarantees k-anonymity. If function localSupp2() cannot be reach k-anonymity, localSupp2 must be re-run on the previous results as long as k-anoymity is reached. If k-anoymity cannot be achieved (because the entries of parameter importance includes too much zeros) the function breaks after a sub-optimal solution is obtained.
