Read a Dataset NDJSON file to a datasetjson object — read_dataset

Reads a newline-delimited JSON (NDJSON) file following the Dataset JSON v1.1.0 specification. Line 1 of the file holds the dataset metadata and each subsequent line holds one data row as a JSON array.

Usage

read_dataset_ndjson(file)

Arguments

file: File path or URL of a Dataset NDJSON file, or a character string containing the NDJSON content itself

Value

A dataframe with additional attributes attached containing the DatasetJSON metadata.

Details

NDJSON and JSON representations of Dataset JSON carry the same content, so the object returned here is the same as the one read_dataset_json() returns for the equivalent .json file, including all of the metadata attached as attributes. See read_dataset_json() for the full list.

Examples

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

# Or from NDJSON text held in memory
ds_json <- dataset_json(
  iris,
  item_oid = "IG.IRIS",
  name = "IRIS",
  dataset_label = "Iris",
  columns = iris_items
)
dat <- read_dataset_ndjson(write_dataset_ndjson(ds_json))
