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)

## Arguments

obj

an object of class data.frame containing micro data

type

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.

n

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

## Value

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