Clear writeAlizer's user cache

Source: R/cache.R
wa_cache_clear.Rd

Deletes all files under wa_cache_dir(). If ask = TRUE and in an interactive session, a short preview (item count, total size, and up to 10 sample paths) is printed before asking for confirmation. In a non-interactive script, no prompt is shown, even if ask = TRUE. Use this only on a dedicated cache folder; all its contents are removed.

Usage

wa_cache_clear(ask = interactive(), preview = TRUE)

Arguments

ask

Logical; if TRUE and interactive, ask for confirmation.

preview

Logical; if TRUE and ask is TRUE, show a brief listing/size summary before asking.

Value

Invisibly returns TRUE if the cache was cleared (or already absent), FALSE if the user declined or deletion failed.
