rdb_dimensions: Download list of dimensions for datasets of DBnomics...

In rdbnomics: Download DBnomics Data

Description

rdb_dimensions downloads the list of dimensions (if they exist) for available datasets of a selection of providers from DBnomics.

Usage

rdb_dimensions(
  provider_code = NULL,
  dataset_code = NULL,
  use_readLines = getOption("rdbnomics.use_readLines"),
  curl_config = getOption("rdbnomics.curl_config"),
  simplify = FALSE,
  ...
)

Arguments

provider_code	Character string (default NULL). DBnomics code of one or multiple providers. If NULL, the providers are firstly dowloaded with the function rdb_providers and then the datasets are requested.
dataset_code	Character string (default NULL). DBnomics code of one or multiple datasets of a provider. If NULL, the datasets codes are dowloaded with the function rdb_datasets and then the dimensions are requested.
use_readLines	Logical (default FALSE). If TRUE, then the data are requested and read with the base function readLines i.e. through the default R internet connection. This can be used to get round the error Could not resolve host: api.db.nomics.world.
curl_config	Named list (default NULL). If not NULL, it is used to configure a proxy connection. This configuration is passed to the function curl_fetch_memory of the package curl. A temporary curl_handle object is created internally with arguments equal to the provided list in curl_config. For curl_fetch_memory arguments see curl_fetch. For available curl options see curl_options, names(curl_options()) and libcurl.
simplify	Logical (default FALSE). If TRUE, when the dimensions are requested for only one provider and one dataset then a named list of data.tables is returned, not a nested named list of data.tables.
...	Additionals arguments.

Details

By default, the function returns a nested named list of data.tables containing the dimensions of datasets for providers from DBnomics.

Value

A nested named list of data.tables or a named list of data.tables.
