Read a Dataset JSON Compressed (DSJC) file to a datasetjson object

Reads the compressed representation of Dataset JSON: a zLib stream holding Dataset NDJSON content. The object returned is the same one read_dataset_json() and read_dataset_ndjson() return for the equivalent uncompressed file, metadata attributes included.

Usage

read_dataset_dsjc(file)

Arguments

file

File path or URL of a DSJC file, or a raw vector holding the compressed bytes

Value

A dataframe with additional attributes attached containing the DatasetJSON metadata.

Examples

# Read one of the example files shipped with the package
dm <- read_dataset_dsjc(datasetjson_example("dm.dsjc"))

# Or from bytes held in memory
ds_json <- dataset_json(
  iris,
  item_oid = "IG.IRIS",
  name = "IRIS",
  dataset_label = "Iris",
  columns = iris_items
)
dat <- read_dataset_dsjc(write_dataset_dsjc(ds_json))
