clear_cache_muni: Delete cached CNEFE data files

In cnefetools: Access and Analysis of Brazilian CNEFE Address Data

Delete cached CNEFE data files

Description

clear_cache_muni() removes CNEFE data files stored in the user cache directory by cnefe_counts(), compute_lumi(), tracts_to_h3(), and related functions.

The cache holds gzipped CSVs (.csv.gz). Archives left by versions before 0.3.0, which cached the ZIP as published by IBGE, are removed as well.

Usage

clear_cache_muni(
  code_muni = "all",
  verbose = TRUE,
  cache_dir = NULL,
  year = NULL
)

Arguments

code_muni	Integer or "all". If "all" (default), every cached CNEFE file is deleted. If a seven-digit IBGE municipality code is provided, only the file for that municipality is deleted.
verbose	Logical; if TRUE (default), reports the number of files deleted and the space freed.
cache_dir	Character. Directory to use for cached downloads. If NULL (default), the CNEFETOOLS_CACHE_DIR environment variable is used when it is set, otherwise tools::R_user_dir() with which = "cache". Use this to point large downloads at a secondary drive or a shared volume.
year	Integer. Restrict the deletion to one CNEFE edition. NULL (default) clears every edition, which is the previous behaviour.

Value

Invisibly, the character vector of deleted file paths.

Examples

# Delete every cached CNEFE file
