contributing_indices: Compute contributing units to table cells

In sdcTable: Methods for Statistical Disclosure Control in Tabular Data

Compute contributing units to table cells

Description

This function computes (with respect to the raw input data) the indices of all contributing units to given cells identified by ids.

Usage

contributing_indices(prob, ids = NULL)

Arguments

prob	a sdcProblem object created with makeProblem()
ids	a character vector containing default ids (strIDs) that define table cells. Valid inputs can be extracted by using sdcProb2df() and looking at column strID. If this argument is NULL, the corresponding units are computed for all cells in the table.

Value

a named ⁠list where names correspond to the given ⁠ids' and the values to the row numbers within the raw input data.

Examples

# loading test problem
p <- sdc_testproblem(with_supps = FALSE)
dt <- sdcProb2df(p, dimCodes = "original")

# question: which units contribute to cell region = "A" and gender = "female"?

# compute the id ("0102")
dt[region == "A" & gender == "female", strID]

# which indices contribute to the cell?
ids <- contributing_indices(prob = p, ids = "0101")

# check
dataObj <- get.sdcProblem(p, "dataObj")
rawData <- slot(dataObj, "rawData")
rawData[ids[["0101"]]]

# compute contributing ids for all cells
contributing_indices(p)
