Compare cached and current DataSUS dictionaries

Usage

compare_datasus_dictionary(
  information_system,
  previous = NULL,
  refresh = TRUE,
  timeout = 240,
  quiet = FALSE,
  cache_dir = getOption("microdatasus.cache_dir", NULL)
)

Arguments

information_system: A value accepted by datasus_variables().
previous: Optional table previously returned by datasus_variables(). When NULL, the currently cached dictionary is used as the baseline.
refresh: Logical scalar. If TRUE, download the current archive after capturing the baseline.
timeout: A positive numeric scalar. Download and connection timeout, in seconds.
quiet: Logical scalar. If TRUE, suppress download progress and status messages.
cache_dir: Optional persistent cache root. The package option microdatasus.cache_dir is used by default; NULL uses only the current session cache.

Value

A tibble describing added, removed, and changed fields, labels, symbolic ranges, or relation states. Column kind identifies the item.
