In expersso/ecb: Programmatic Access to the European Central Bank's Statistical Data Warehouse

Description

Retrieve data from the ECB Statistical Data Warehouse API

Usage

get_data(key, filter = NULL, ...)

Arguments

key	A character string identifying the series to be retrieved
filter	A named list with additional filters (see details)
...	Arguments passed to GET (e.g. timeout(10) to add maximum request time)

Details

The filter option of get_data() takes a named list of key-value pairs. If left blank, it returns all data for the current version.

Available filter parameters:

• startPeriod & endPeriod

  • YYYY for annual data (e.g.: 2013)

  • YYYY-S[1-2] for semi-annual data (e.g.: 2013-S1)

  • YYYY-Q[1-4] for quarterly data (e.g.: 2013-Q1)

  • YYYY-MM for monthly data (e.g.: 2013-01)

  • YYYY-W[01-53] for weekly data (e.g.: 2013-W01)

  • YYYY-MM-DD for daily data (e.g.: 2013-01-01)

• updatedAfter

  • A timestamp to retrieve the latest version of changed values in the database since a certain point in time

  • Example: filter = list(updatedAfter = 2009-05-15T14:15:00+01:00)

• firstNObservations & lastNObservations

  • Example: filter = list(firstNObservations = 12) retrieves the first 12 observations of all specified series

• detail

  • Possible options: full/dataonly/serieskeysonly/nodata

  • dataonly is the default

  • Use serieskeysonly or nodata to list series that match a certain query, without returning the actual data

  • An alternative to using serieskeys/nodata is the convenience function get_dimensions(), which returns a list of dataframes with dimensions and explanations (see extended example below).

  • full returns both the series values and all metadata. This entails retrieving much more data than with the 'dataonly' option.

• includeHistory (not currently implemented)

  • false (default) returns only version currently in production

  • true returns version currently in production, as well as all previous versions

See the SDW API for more details.

Value

A data frame

hicp <- get_data("ICP.M.U2.N.000000.4.ANR")
head(hicp)
