`nccs_read()` downloads the geocoded master BMF parquet (hundreds of MB)
from S3 on first use and reuses a local copy on subsequent calls. These
helpers expose the cache directory used by default and let you wipe it.
Usage
nccs_cache_dir()
nccs_cache_clear(dir = nccs_cache_dir())
Arguments
- dir
Directory to clear. Defaults to [nccs_cache_dir()].
Value
`nccs_cache_dir()` returns the cache directory as a character
string. `nccs_cache_clear()` returns the number of files removed,
invisibly.
Details
The default location is `tools::R_user_dir("nccsdata", "cache")`. The
cached file is considered stale after `cache_max_age` days (30 by
default; the upstream master is rebuilt monthly).
Examples
nccs_cache_dir()
#> [1] "/home/runner/.cache/R/nccsdata"
if (FALSE) { # \dontrun{
# Force a refresh on the next nccs_read() call
nccs_cache_clear()
} # }
