Loads or downloads the necessary data for all modules — load_or_download

Either downloads the necessary data for all modules from Eurostat using dataset ids or loads the files provided in the user-specified input directory and selects the required variables.

Usage

load_or_download_variables(
  specification,
  dictionary = NULL,
  primary_source = c("download", "local"),
  input = NULL,
  save_to_disk = NULL,
  quiet = FALSE,
  constrain.to.minimum.sample = TRUE
)

Arguments

specification: A tibble or data.frame as returned by check_config_table.
dictionary: A tibble or data.frame storing the Eurostat variable code in column 'eurostat_code'. If download == TRUE then the dictionary also requires column named 'dataset_id' that stores the Eurostat dataset id. When NULL, the default dictionary is used.
primary_source: A character of length 1 determining whether the required variables are first obtained from "download" and then "local"ly or vice versa.
input: A character vector of file paths, a data.frame, or a list of data.frames or file paths. Required if download == FALSE and at least one variable is specified as coming from a local source.
save_to_disk: A path to a directory where the final dataset will be saved, including file name and ending. Not saved when NULL.
quiet: Logical with default = FALSE. Should messages be displayed? These messages are intended to give more information about the estimation and data retrieval process.
constrain.to.minimum.sample: Logical. Should all data series be constrained to the minimum data series? Default is TRUE.
