DBnomics R client

This package provides you access to DBnomics data series. DBnomics is an open-source project with the goal of aggregating the world's economic data in one location, free of charge to the public. DBnomics covers hundreds of millions of series from international and national institutions (Eurostat, World Bank, IMF, ...).

To use this package, you have to provide the codes of the provider, dataset and series you want. You can retrieve them directly on the website. You have access to the API through this link and the documentation is here.

DBnomics is hosted on its own gitlab platform. However, in order to install the package more easily, we created a mirror of this package on github.

To install rdbnomics from CRAN :


To install rdbnomics from github :

remotes::install_github("dbnomics/rdbnomics", build = TRUE, build_opts = c("--no-resave-data", "--no-manual"), force = TRUE)

After installation, a vignette is available to the user :



Fetch time series by ids :

# Fetch one series from dataset 'Unemployment rate' (ZUTN) of AMECO provider :
df1 <- rdb(ids = 'AMECO/ZUTN/EA19.')
# Fetch two series from dataset 'Unemployment rate' (ZUTN) of AMECO provider :
df2 <- rdb(ids = c('AMECO/ZUTN/EA19.', 'AMECO/ZUTN/DNK.'))
# Fetch two series from different datasets of different providers :
df3 <- rdb(ids = c('AMECO/ZUTN/EA19.', 'IMF/CPI/A.AT.PCPIT_IX'))

In the event that you only use the argument ids, you can drop it and run :

df <- rdb('AMECO/ZUTN/EA19.')

Fetch time series by mask :

# Fetch one series from dataset 'Consumer Price Index' (CPI) of IMF :
df1 <- rdb('IMF', 'CPI', mask = 'M.DE.PCPIEC_WT')
# Fetch two series from dataset 'Consumer Price Index' (CPI) of IMF :
df2 <- rdb('IMF', 'CPI', mask = 'M.DE+FR.PCPIEC_WT')
# Fetch all series along one dimension from dataset 'Consumer Price Index' (CPI) of IMF :
df3 <- rdb('IMF', 'CPI', mask = 'M..PCPIEC_WT')
# Fetch series along multiple dimensions from dataset 'Consumer Price Index' (CPI) of IMF :
df4 <- rdb('IMF', 'CPI', mask = 'M..PCPIEC_IX+PCPIA_IX')

In the event that you only use the arguments provider_code, dataset_code and mask, you can drop the name mask and run :

df <- rdb('IMF', 'CPI', 'M.DE.PCPIEC_WT')

Fetch time series by dimensions :

# Fetch one value of one dimension from dataset 'Unemployment rate' (ZUTN) of AMECO provider :
df1 <- rdb('AMECO', 'ZUTN', dimensions = list(geo = "ea12"))
# or
df1 <- rdb('AMECO', 'ZUTN', dimensions = '{"geo": ["ea12"]}')
# Fetch two values of one dimension from dataset 'Unemployment rate' (ZUTN) of AMECO provider :
df2 <- rdb('AMECO', 'ZUTN', dimensions = list(geo = c("ea12", "dnk")))
# or
df2 <- rdb('AMECO', 'ZUTN', dimensions = '{"geo": ["ea12", "dnk"]}')
# Fetch several values of several dimensions from dataset 'Doing business' (DB) of World Bank :
df3 <- rdb('WB', 'DB', dimensions = list(country = c("DZ", "PE"), indicator = c("ENF.CONT.COEN.COST.ZS", "IC.REG.COST.PC.FE.ZS")))
# or
df3 <- rdb('WB', 'DB', dimensions = '{"country": ["DZ", "PE"], "indicator": ["ENF.CONT.COEN.COST.ZS", "IC.REG.COST.PC.FE.ZS"]}')

Fetch one series from the dataset 'Doing Business' of WB provider with the link :

df1 <- rdb_by_api_link('')

Proxy configuration or connection error Could not resolve host

When using the functions rdb or rdb_..., you may come across the following error :

Error in open.connection(con, "rb") :
  Could not resolve host:

To get round this situation, you have two possibilities :

  1. configure curl to use a specific and authorized proxy.

  2. use the default R internet connection i.e. the Internet Explorer proxy defined in internet2.dll.

Configure curl to use a specific and authorized proxy

In rdbnomics, by default the function curl_fetch_memory (of the package curl) is used to fetch the data. If a specific proxy must be used, it is possible to define it permanently with the package option rdbnomics.curl_config or on the fly through the argument curl_config. In that way the object is passed to the argument handle of the curl_fetch_memory function.
To see the available parameters, run names(curl_options()) in R or visit the website Once they are chosen, you define the curl object as follows :

h <- curl::new_handle(
  proxy = "<proxy>",
  proxyport = <port>,
  proxyusername = "<username>",
  proxypassword = "<password>"

Set the connection up for a session

The curl connection can be set up for a session by modifying the following package option :

options(rdbnomics.curl_config = h)

When fetching the data, the command curl_fetch_memory(url = <...>, handle = h) is executed. In the event that you want to add others arguments, use :

options(rdbnomics.curl_config = list(handle = h, arg = <...>))

After configuration, just use the standard functions of rdbnomics e.g. :

df1 <- rdb(ids = 'AMECO/ZUTN/EA19.')

This option of the package can be disabled with :

options(rdbnomics.curl = NULL)

Use the connection only for a function call

If a complete configuration is not needed but just an "on the fly" execution, then use the argument curl_config of the functions rdb and rdb_... :

df1 <- rdb(ids = 'AMECO/ZUTN/EA19.', curl_config = h)

Use the default R internet connection

To retrieve the data with the default R internet connection, rdbnomics will use the base function readLines.

Set the connection up for a session

To activate this feature for a session, you need to enable an option of the package :

options(rdbnomics.use_readLines = TRUE)

And then use the standard function as follows :

df1 <- rdb(ids = 'AMECO/ZUTN/EA19.')

This configuration can be disabled with :

options(rdbnomics.use_readLines = FALSE)

Use the connection only for a function call

If you just want to do it once, you may use the argument use_readLines of the functions rdb and rdb_... :

df1 <- rdb(ids = 'AMECO/ZUTN/EA19.', use_readLines = TRUE)

rdbnomics 0.4.6

  • Internal function deploy better handles recursive lists.

rdbnomics 0.4.5

  • The vignette "rdbnomics-tutorial" is now named "rdbnomics".
  • rdb() and rdb_...() functions now have an argument to configure curl. It is also an option of the package. The vignette "rdbnomics" is modified consequently.
  • rdb() and rdb_by_api_link() functions return an error if the columns period and period_start_day don't exist.
  • rdb() function passes argument provider_code to ids if only provider_code is provided. It is considered that the user wants to use ids without naming the arguments.
  • rdb() function passes argument ids to mask if only provider_code, dataset_code and ids are provided. It is considered that the user wants to use mask without naming the argument.

rdbnomics 0.4.4

  • Change of the API version from 21 to 22.
  • The vignette "rdbnomics-tutorial" is modified to be backward compatible with R Markdown v1 (i.e. without pandoc or rmarkdown).
  • The vignette "rdbnomics-tutorial" has an appendix.
  • New rdb_providers() returns the available providers.
  • New rdb_last_updates() shows the last updates.
  • In the functions, dates and timestamps are transformed using as.Date() and as.POSIXct().
  • dimensions in rdb() can be a list (@Iwo, #1).

rdbnomics 0.4.3

  • First release on CRAN.
