writeJJFormat {sdcTable}

Write a problem in jj-format to a file

Description

This function allows to write a problem instance in JJ-Format to a file.

Usage

writeJJFormat(x, tabvar = "freqs", path = "out.jj", overwrite = FALSE)

Arguments

x

an input produced by createJJFormat()

tabvar

the name of the variable that will be used when producing the problem in JJ format. It is possible to specify freqs (the default) or the name of a numeric variable that was available in the sdcProblem object used in makeProblem().

path

a scalar character defining the name of the file that should be written. This can be an absolute or relative URL; however the file must not exist.

overwrite

logical scalar, if TRUE the file specified in path will be overwritten if it exists

Value

invisibly the path to the file that was created.

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
)
