catrnav_set_cache_dir()
will store your cache_dir
path on your local
machine and would load it for future sessions.
Alternatively, you can store the cache_dir
manually with the following
options:
Run
Sys.setenv(CATASTRONAV_CACHE_DIR = "cache_dir")
. You would need to run this command on each session (Similar toinstall = FALSE
).Write this line on your .Renviron file:
CATASTRONAV_CACHE_DIR = "value_for_cache_dir"
(same behavior thaninstall = TRUE
). This would store yourcache_dir
permanently.
catrnav_detect_cache_dir()
detects and returns the path to your current
cache_dir
.
Usage
catrnav_set_cache_dir(
cache_dir,
overwrite = FALSE,
install = FALSE,
verbose = TRUE
)
catrnav_detect_cache_dir(...)

catrnav_set_cache_dir()

session
About caching
Sometimes cached files may be corrupt. On that case, try re-downloading
the data setting update_cache = TRUE
.
If you experience any problem on download, try to download the
corresponding file by any other method and save it on your
cache_dir
. Use the option verbose = TRUE
for debugging the API query.
