module: Character. Filter by module code (e.g., "J", "K", "L"). NULL returns all modules. Default is NULL.
cache_dir: Character. Directory for caching downloaded files. Default uses tools::R_user_dir("healthbR", "cache").
refresh: Logical. If TRUE, re-download even if file exists in cache. Default is FALSE.

Value

A tibble with variable names and labels.

Examples

if (FALSE) { # interactive()
# list all variables for 2019
