Inspect the readnoaa cache

Source: R/cache.R
cache_info.Rd

Lists the cached responses currently on disk, with their size and age. Useful for checking whether a result is being served from a stale copy.

Usage

cache_info()

Value

A data frame with columns file, size_kb, and age_days, returned invisibly if the cache is empty.

Details

Cached responses expire automatically. Requests whose window ends within the last five weeks are treated as provisional and expire after one day, because NCEI publishes recent observations with a lag and continues to revise them. Older windows are treated as settled and expire after 30 days. Both thresholds are configurable through the options readnoaa.cache_days_recent and readnoaa.cache_days, and any single call can bypass the cache entirely with refresh = TRUE.
