View source: R/extractor_functions.R

Extracts variables in the V-Dem dataset (version 11), by using a filter expression that is used to extract variable names from the V-Dem coddebook (vdem_codebook)

extract_vdem_filter(
  ...,
  include_uncertainty = TRUE,
  include_sd = FALSE,
  include_osp = FALSE,
  include_ord = FALSE,
  include_nr = FALSE,
  include_external = FALSE
)

`...`	A sequence of filter expressions, separated by commas, suitable for use with dplyr::filter, operating on the column names of vdem_codebook. See examples.
`include_uncertainty`	Whether to return the uncertainty measurements for the selected variables (`codelow` and `codehigh` suffixes). Default is `TRUE`.
`include_sd`	Whether to return the standard deviation for the selected variables (`sd` suffix). Default is `FALSE`.
`include_osp`	Whether to return variables available in the original scale (`osp` suffix, linearized original scale posterior prediction). Default is `FALSE`.
`include_ord`	Whether to return variables available in an ordinal scale (`ord` suffix, measurement model estimates of original scale value). Default is `FALSE`.
`include_nr`	Whether to return the number of coders for the variable (`nr` suffix). Default is `FALSE`.
`include_external`	Whether to return variables marked "external", i.e., coming from an external source rather than V-Dem (`e_` prefix). Default is `FALSE`.

A tibble with the V-Dem country identifiers, other state system identifiers, plus the desired variables.
