allows to restrict original data to only a subset. This may be useful to test some anonymization methods. This function will only be used in the graphical user interface sdcApp.

subsetMicrodata(obj, type, n)



an object of class data.frame containing micro data


algorithm used to sample from original microdata. Currently supported choices are

  • n_perc the restricted microdata will be a n-percent sample of the original microdata.

  • first_n only the first n observations will be used.

  • every_n the restricted microdata set consists of every n-th record.

  • size_n a total of n observations will be randomly drawn.


numeric vector of length 1 specifying the specific parameter with respect to argument type.


an object of class sdcMicroObj-class with modified slot @origData.
