In sdcTable: Methods for Statistical Disclosure Control in Tabular Data

Set/Update information in sdcProblem or problemInstance objects

Description

Function setInfo() is used to update values in sdcProblem or problemInstance objects

Usage

setInfo(object, type, index, input)

Arguments

object	an object of class sdcProblem or problemInstance
type	a scalar character specifying the kind of information that should be changed or modified; if object inherits class problemInstance, the slots are directly changed, otherwise the values within slot problemInstance are updated. Valid choices are: lb: lower possible bounds for the cell ub: max. upper bound for the given cell LPL: lower protection level SPL: sliding protection level UPL: upper protection level sdcStatus: cell-status
index	numeric vector defining cell-indices for which which values in a specified slot should be changed|modified
input	numeric or character vector depending on argument type with its length matching the length of argument index character vector if type matches 'sdcStatus' a numeric vector if type matches 'lb', 'ub', 'LPL', 'SPL' or 'UPL'

Value

a sdcProblem- or problemInstance object

Examples

# load example-problem with suppressions
# (same as example from ?primarySuppression)
p <- sdc_testproblem(with_supps = TRUE)

# which is the overall total?
idx <- which.max(getInfo(p, "freq")); idx

# we see that the cell with idx = 1 is the overall total and its
# anonymization state of the total can be extracted as follows:
print(getInfo(p, type = "sdcStatus")[idx])

# we want this cell to never be suppressed
p <- setInfo(p, type = "sdcStatus", index = idx, input = "z")

# we can verify this:
print(getInfo(p, type = "sdcStatus")[idx])

# changing slot 'UPL' for all cells
inp <- data.frame(
  strID = getInfo(p, "strID"),
  UPL_old = getInfo(p, "UPL")
)
inp$UPL_new <- inp$UPL_old + 1
p <- setInfo(p, type = "UPL", index = 1:nrow(inp), input = inp$UPL_new)
