Scans hidden R temporary directories for abandoned session data and caches, categorizes the storage waste, and interactively prompts the user for safe deletion to reclaim disk space.
Value
Invisibly returns a named list with components: status ("done",
"clean", or "cancelled"), dirs_found (integer), and
space_freed_mb (numeric).
Details
The function performs a deep scan of the OS-level temporary directory where R stores session data:
Identifies all directories matching the `RtmpXXXXXX` pattern.
Scans these directories and categorizes files into buckets:
Knitr/RMarkdown Caches: `.knit.md`, `.utf8.md`, and `_cache` files.
Downloaded Packages: `.tar.gz`, `.zip`, and `.tgz` files.
Raster/Image Files: `.tif`, `.png`, `.jpg`, and `.grd` files.
General Session Data: All other temporary files.
Calculates the total size of each bucket in megabytes.
Interactively prompts the user to select which buckets to permanently flush.
Warning
This function modifies files on disk or the global environment. Please ensure you have a backup or are using version control (e.g., Git) before execution.
