print.sdcMicroObj function

Print and Extractor Functions for objects of class sdcMicroObj-class

Descriptive print function for Frequencies, local Supression, Recoding, categorical risk and numerical risk. methods

## S4 method for signature 'sdcMicroObj'
print(x, type = "kAnon", docat = TRUE, ...)

Arguments

• x: An object of class sdcMicroObj-class

• type: Selection of the content to be returned or printed

• docat: logical, if TRUE (default) the results will be actually printed

• ...: the type argument for the print method, currently supported are:

  • general: basic information on the input obj such as the number of observations and variables.
  • kAnon: displays information about 2- and 3-anonymity
  • ls: displays various information if local suppression has been applied.
  • pram: displays various information if post-randomization has been applied.
  • recode: shows information about categorical key variables before and after recoding
  • risk: displays information on re-identification risks
  • numrisk: displays risk- and utility measures for numerical key variables

Details

Possible values for the type argument of the print function are: "freq": for Frequencies, "ls": for Local Supression output, "pram": for results of post-randomization "recode":for Recodes, "risk": forCategorical risk and "numrisk": for Numerical risk.

Possible values for the type argument of the freq function are: "fk": Sample frequencies and "Fk": weighted frequencies.

Examples

data(testdata)

sdc <- createSdcObj(testdata,
  keyVars=c('urbrur','roof','walls','relat','sex'),
  pramVars=c('water','electcon'),
  numVars=c('expend','income','savings'), w='sampling_weight')
sdc <- microaggregation(sdc, method="mdav", aggr=3)
print(sdc)
print(sdc, type="general")
print(sdc, type="ls")
print(sdc, type="recode")
print(sdc, type="risk")
print(sdc, type="numrisk")
print(sdc, type="pram")
