rdbnomics (version 0.6.4)

rdb_datasets: Download list of datasets for DBnomics providers.

Description

rdb_datasets downloads the list of available datasets for a selection of providers (or all of them) from DBnomics.

Usage

rdb_datasets(
  provider_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 available datasets 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 datasets are requested for only one provider then a data.table is returned, not a list of data.tables.

...

Additionals arguments.

Value

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

Details

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