write_dataset_json: Write out a Dataset JSON file

In datasetjson: Read and Write CDISC Dataset JSON Files

Write out a Dataset JSON file

Description

Write out a Dataset JSON file

Usage

write_dataset_json(
  x,
  file,
  pretty = FALSE,
  float_as_decimals = FALSE,
  digits = 16
)

Arguments

x	datasetjson object
file	File path to save Dataset JSON file
pretty	If TRUE, write with readable formatting. Note: The Dataset JSON standard prefers compressed formatting without line feeds. It is not recommended you use pretty printing for submission purposes.
float_as_decimals	If TRUE, Convert float variables to "decimal" data type in the JSON output. This will manually convert the numeric values using the format() function using the number of digits specified in digits, bypassing the yyjsonr handling of float values and writing the numbers out as JSON character strings. See the Dataset JSON user guide for more information. Defaults to FALSE
digits	When using float_as_decimals, the number of digits to use when writing out floats. Going higher than 16 may start writing otherwise sufficiently precise decimals (i.e. .2) to long strings.

Value

NULL when file written to disk, otherwise character string

Examples

# Write to character object
ds_json <- dataset_json(
  iris,
  item_oid = "IG.IRIS",
  name = "IRIS",
  dataset_label = "Iris",
  columns = iris_items
)
js <- write_dataset_json(ds_json)

# Write to disk
## Not run: 
  write_dataset_json(ds_json, "path/to/file.json")

## End(Not run)
