Examples

# setup example problem
# microdata
utils::data("microdata1", package = "sdcTable")

# create hierarchies
dims <- list(
  region = sdcHierarchies::hier_create(root = "Total", nodes = LETTERS[1:4]),
  gender = sdcHierarchies::hier_create(root = "Total", nodes = c("male", "female")))

# create a problem instance
p <- makeProblem(
  data = microdata1,
  dimList = dims,
  numVarInd = "val")

# create suitable input for `writeJJFormat`
inp <- createJJFormat(p); inp

# write files to disk
# frequency table by default
writeJJFormat(
  x = inp,
  path = file.path(tempdir(), "prob_freqs.jj"),
  overwrite = TRUE
)

# or using the numeric variable `val` previously specified
writeJJFormat(
  x = inp,
  tabvar = "val",
  path = file.path(tempdir(), "prob_val.jj"),
  overwrite = TRUE
)
