Package 'eurodata'

Coerce a data.frame to a EurostatDataList

Description

Some manipulations of the EurostatDataList data.frame (imported with importDataList) e.g. filtering with package dplyr may remove the S3 class tag EurostatDataList. This function coerces it back to EurostatDataList after checking that the critical columns (PCode, Dataset name,Link) are present. This is useful if a user wants to print and browse this filtered data.frame as a specially formatted HTML table.

Usage

as.EurostatDataList(x, SearchCriteria = "", ...)

Arguments

x	A (most likely filtered subset of) EurostatDataList data.frame returned by importDataList.
SearchCriteria	A string describing the search criteria used for filtering/subsetting.
...	Additional arguments to be passed to or from methods (currently not used).

Value

A data.frame of S3 class EurostatDataList.

Value

• Side effect (via print) – a table opened in a browser via browseURL.

• Value – a list with:

  • criteria – a string, search criteria,

  • time – the time of the query,

  • df – a data.frame, imported via importDataList and filtered based on the conditions specified in subs.

Describe a given Eurostat dataset on the basis of information from Metabase

Description

Describe a given Eurostat dataset on the basis of information from Metabase

Usage

describe(
  EurostatDatasetCode,
  import_labels = !wide,
  wide = FALSE,
  import_dim_labels = TRUE
)

Arguments

EurostatDatasetCode	A string with Eurostat dataset code name, e.g. "nama_10_gdp" or "bop_its6_det". See e.g.: https://ec.europa.eu/eurostat/databrowser/explore/all/all_themes where, once you follow one of the "branches" of the "tree" of datasets, the dataset codes are in tiny grey font in square brackets just under the full names of the datasets (the names are in navy blue and preceded by a cube icon).
import_labels	Boolean: should labels for the codes inside dimensions be imported. Default: if wide is FALSE then import_labels is TRUE and vice versa.
wide	Boolean: should each dimension be compressed to one row and all values within each dimension to a single, comma-separated string. Default: FALSE.
import_dim_labels	Boolean: should the dimensions (e.g. geo, indic_is, or nace_r2) be labelled with a descriptive name (via importDimLabel). Default: TRUE.

Value

A data.table with columns Dim_name, Dim_name_label (if import_dim_labels=TRUE), either Dim_val (if wide=FALSE) or Dim_values (if wide=TRUE), Dim_val_label (if import_labels=TRUE), and a column with a name = EurostatDatasetCode with all its values = TRUE.

Examples

## Not run: 
describe('nama_10_gdp')

## End(Not run)

Search Eurostat datasets and see the result as text

Description

A tool for a quick ad-hoc search.

Usage

find(...)

Arguments

...

A series of unquoted words to be searched either in Eurostat dataset codes or in dataset full names. All words not preceded by minus (-) will be linked with logical AND; all words preceded by a minus entail exclusion (logical NOT), a bit like in Google search. It is possible to search also with phrases that include spaces – in such a case the phrases should be quoted. Partial word/phrase match is applied. See the examples below.

Value

• Side effect (via print) – a text report file opened via file.show.

• Value – a list with:

  • criteria – a string, search criteria,

  • time – the time of the query,

  • df – a data.frame, imported via importDataList and filtered based on the conditions specified in ...,

  • report – a string, with the text report.

Examples

## Not run: 
find(bop, its)
find(bop,-ybk,its)
find(nama_)
find(nama,10,64)
find('economic indic')

## End(Not run)

Download and import a Eurostat dataset

Description

Download and import a Eurostat dataset

Usage

importData(EurostatDatasetCode, filters = NULL)

Arguments

EurostatDatasetCode

A string (upper/lower-case difference is not relevant) with Eurostat dataset code name, e.g. nama_10_gdp or bop_its6_det. See https://ec.europa.eu/eurostat/databrowser/explore/all/all_themes to find a dataset code – the dataset codes are in tiny font in square brackets.

filters

Optional: a list of atomic vectors. The names of the elements of the list should correspond to the names of the dimensions of the dataset (defined in EurostatDatasetCode), e.g. geo, nace_r2, indic_esb etc. The elements of each vector in that list should correspond to each respective dimension's values available in the dataset. Only these dimension values will be downloaded. For TIME_PERIOD it's enough to provide 1 or 2 values – the lowest one will be used as a start of the data period and the highest as the end of the data period downloaded. Use filters if you need only a few dimension values as it will be faster than downloading the full dataset.

Value

A Eurostat dataset as a ‘flat’ data.frame. A ‘flat’ dataset has all numeric values in one column, with each row representing one of the available combinations of all dimensions (e.g. if dimensions are: countries, years, sectors, and indicators, there can be a row for value added in retail in Germany in 2013).

Examples

## Not run: 
# Full dataset import:
importData('nama_10_gdp')
# Import only a subset of a dataset:
importData('bop_its6_det',
           filters = list(geo=c('AT','BG'),
                          TIME_PERIOD=2014:2020,
                          bop_item='SC'))

## End(Not run)
