: Zip Code Tabulation AreasBy default, downloading will print status messages and/or a progress bar. For silent downloads, set options(tinytiger.curl_quiet = TRUE)
.
Downloads will go to options(tinytiger.cache_dir)
if it is set. If it is not, and rappdirs
is installed, and options(tinytiger.use_cache = TRUE)
, downloads will be cached between sessions in rappdirs::user_cache_dir("tinytiger")
. If it is not installed, or if options(tinytiger.use_cache = FALSE)
, then the cache will be in a temporary directory that does not persist between sessions. You can check the size of the cache and clear it with tt_cache_size()
and tt_cache_clear()
.
