Clear the on-disk / in-memory WDI cache — clear_wdi

Forget memoised World Bank fetches, both in-session and (optionally) on disk.

Usage

clear_wdi_cache(disk = FALSE)

Arguments

disk: Whether to also delete the persistent on-disk cache.

Value

Invisibly TRUE.

Where the cache lives

The persistent cache goes in the standard per-user cache location, tools::R_user_dir("countryatlas", "cache"). Point it elsewhere with options(countryatlas.cache_dir = ), or skip the disk entirely by passing cache = FALSE to world_data() / country_data(). Nothing is written until a World Bank fetch actually succeeds, so a purely offline session (examples, tests, the bundled world_snapshot) never creates it.

Examples

clear_wdi_cache()              # forget the in-session memo
if (FALSE) { # \dontrun{
clear_wdi_cache(disk = TRUE)   # also delete the persistent cache
} # }
