Get All Available Classes from Data Commons — dc_get

A convenience wrapper around dc_get_node() to retrieve all available entity classes in Data Commons. This is equivalent to calling dc_get_node() with nodes = "Class" and expression = "<-typeOf".

dc_get_classes(
  api_key = Sys.getenv("DATACOMMONS_API_KEY"),
  base_url = Sys.getenv("DATACOMMONS_BASE_URL", unset =
    "https://api.datacommons.org/v2/"),
  return_type = "json"
)

Arguments

api_key: Your Data Commons API key. If not provided, will use the environment variable DATACOMMONS_API_KEY.
base_url: The base URL of the Data Commons API. Defaults to the public endpoint. For custom deployments, it must end with "/core/api/v2/".
return_type: Return format: either "list" (parsed R object) or "json" (JSON string).

Value

A list (if return_type = "list") or JSON string (if return_type = "json") containing all available entity classes.

Examples

if (FALSE) { # dc_has_api_key()
# Get all entity classes
all_classes <- dc_get_classes(return_type = "json")
}
