bbk_cache_dir() returns the path where cached API responses are stored.
bbk_cache_clear() clears all cached responses.
Value
bbk_cache_dir() returns a string with the path to the cache directory.
bbk_cache_clear() is called for its side effect of clearing the cached
responses and returns NULL invisibly.
Details
The cache is only used when enabled with options(bbk.cache = TRUE).
Each API's caching headers decide whether and for how long a cached response is reused, so the cache helps more with some APIs than others. APIs that allow reuse do so for minutes rather than hours. Others check a cached response with the API on every call, which only saves downloading it again, and many don't allow caching at all.
Cached responses older than 1 day are deleted. Change this with
options(bbk.cache_max_age = seconds). A higher value doesn't make responses be reused for
longer than the API allows.
Examples
if (FALSE) { # \dontrun{
# enable caching
options(bbk.cache = TRUE)
# view cache location
bbk_cache_dir()
# clear the cache
bbk_cache_clear()
} # }
