Deletes all raw ACS query results cached by
compile_acs_data(cache = TRUE).
Value
The number of cache files removed, invisibly.
Details
Cached files live in
tools::R_user_dir("urbnindicators", which = "cache"), or in the
directory named by options(urbnindicators.cache_dir = ...) when
set. Because ACS estimates do not change, cached
entries never go stale; clearing the cache is only useful to reclaim
disk space.
Examples
if (FALSE) { # \dontrun{
clear_acs_cache()
} # }
