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

setInfo(object, type, index, input)



an object of class sdcProblem or problemInstance


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


numeric vector defining cell-indices for which which values in a specified slot should be changed|modified


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'


a sdcProblem- or problemInstance object

# 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
#> [1] 1

# 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])
#> [1] "s"

# 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])
#> [1] "z"

# 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)
