Retrieve data from Eurostat API in JSON format.

Usage

1
2
get_eurostat_json(id, filters = NULL, type = c("code", "label", "both"),
  lang = c("en", "fr", "de"), stringsAsFactors = default.stringsAsFactors())

Arguments

id

A code name for the dataset of interested. See the table of contents of eurostat datasets for more details.

filters

A named list of filters. Names of list objects are Eurostat variable codes and values are vectors of observation codes. If NULL (default) the whole dataset is returned. See details for more on filters and limitations per query.

type

A type of variables, "code" (default), "label" or "both". The "both" will return a data_frame with named vectors, labels as values and codes as names.

lang

A language used for metadata (en/fr/de).

stringsAsFactors

if TRUE (the default) variables are converted to factors in original Eurostat order. If FALSE they are returned as a character.

Details

Data to retrieve from The Eurostat Web Services can be specified with filters. Normally, it is better to use JSON query through get_eurostat, than to use get_eurostat_json directly.

Queries are limited to 50 sub-indicators at a time. A time can be filtered with fixed "time" filter or with "sinceTimePeriod" and "lastTimePeriod" filters. A sinceTimePeriod = 2000 returns observations from 2000 to a last available. A lastTimePeriod = 10 returns a 10 last observations.

Value

A dataset as a data_frame.
