get_ilostat: Read Ilostat Data

Description

Download datasets from ilostat https://ilostat.ilo.org via bulk download facility https://ilostat.ilo.org/data/bulk/.

Usage

get_ilostat(
  id,
  segment = getOption("ilostat_segment", "indicator"),
  type = getOption("ilostat_type", "code"),
  lang = getOption("ilostat_lang", "en"),
  time_format = getOption("ilostat_time_format", "raw"),
  filters = getOption("ilostat_filter", "none"),
  fixed = getOption("ilostat_fixed", TRUE),
  detail = getOption("ilostat_detail", "full"),
  cache = getOption("ilostat_cache", TRUE),
  cache_update = getOption("ilostat_cache_update", TRUE),
  cache_dir = getOption("ilostat_cache_dir", NULL),
  cache_format = getOption("ilostat_cache_format", "rds"),
  back = getOption("ilostat_back", TRUE),
  cmd = getOption("ilostat_cmd", "none"),
  quiet = getOption("ilostat_quiet", FALSE)
)

Value

a tibble. One column for each dimension in the data and the values column for numerical values, as well as the metadata columns. The time column for a time dimension.

Arguments

id

A code name for the dataset of interest. See get_ilostat_toc or details for how to get code.

segment

A character, way to get datasets by: "indicator" (default) or "ref_area". Can be set also with options(ilostat_segment = 'ref_area'),

type

a character, type of variables, "code" (default), "label" or "both". Can be set also with options(ilostat_type = 'both'),

lang

a character, code for language. Available are "en" (default), "fr" and "es". Can be set also with options(ilostat_lang = 'fr'),

time_format

a string giving a type of the conversion of the time column from the ilostat format. "raw" (default) does not do conversion and return time as character (ie. '2017', '2017Q1', '2017M01'). A "date" converted to a Date with a first date of the period. A "date_last" converted to a Date with a last date of the period and "num" converted to a numeric. Can be set also with options(ilostat_time_format = 'date'),

filters

a list; "none" (default) to get a whole dataset or a named list of filters to get just part of the table. Names of list objects are ilostat variable codes and values are vectors of observation codes. filters detect on variables, so could be partial, ie. list(sex = 'T') is enough but equivalent to list(sex = 'SEX_T'). Additional options:

• timefrom : starting year of the return dataset,

• timeto : ending year of the return dataset.

fixed

a logical, if TRUE (default), filters arguments pattern is a string to be matched as is, Change to FALSE if more complex regex matching is needed.

detail

a character, 'full' (default), whether 'serieskeysonly', return only key, no data, no notes or dataonly return key and data, no notes or 'bestsourceonly' return best source only at the series key levels, see details. Can be set also with options(ilostat_detail = 'serieskeysonly'),

cache

a logical whether to do caching. Default is TRUE. Affects only queries from the ilostat bulk download facility. Can be set also with options(ilostat_cache = FALSE),

cache_update

a logical whether to update cache. Check cache update with last.update attribute store on the cache file name and the one from the table of contents. Can be set also with options(ilostat_cache_update = FALSE). Default is TRUE,

cache_dir

a path to a cache directory. The directory has to exist. The NULL (default) uses and creates 'ilostat' directory in the temporary directory from tempdir. The directory can also be set with option ilostat_cache_dir,

cache_format

a character, format to store on the cache "rds" (default), but also "csv", "dta", "sav", "sas7bdat". useful for getting ilostat dataset directly on the cache_dir without R. Can be set also with options(ilostat_cache_format = 'dta'),

back

a logical, TRUE return dataframe on R or not FALSE, useful for just saving file in specific cache_format,

cmd

a character, R expression use for manipulate internal data frame dat object applied to each datasets retrieved If use, cache is set to FALSE. see examples.

quiet

a logical, if TRUE , don't return message from processing, FALSE (default). Can be set also with options(ilostat_quiet = TRUE),

others

Data sets are downloaded from the ilostat bulk download facility. If only the table id is given, the whole table is downloaded from the bulk download facility.

The bulk download facility is the fastest method to download whole datasets. It is also often the only way as the sdmx API has limitation of maximum 300 000 records at the same time and whole datasets usually exceeds that.

By default datasets from the bulk download facility are cached as they are often rather large.

Cache files are stored in a temporary directory by default or in a named directory if cache_dir or option ilostat_cache_dir is defined. The cache can be emptied with clean_ilostat_cache.

The id, a code, for the dataset can be searched with the get_ilostat_toc or from the [bulk download facility](https://ilostat.ilo.org/data/bulk/).
