Do garbage collection on the drake cache.

Garbage collection removes obsolete target values from the cache.

Usage

drake_gc(
  path = NULL,
  search = NULL,
  verbose = NULL,
  cache = drake::drake_cache(path = path),
  force = FALSE
)

Arguments

path

Path to a drake cache (usually a hidden .drake/ folder) or NULL.

search

Deprecated.

verbose

Deprecated on 2019-09-11.

cache

drake cache. See new_cache(). If supplied, path is ignored.

force

Logical, whether to load the cache despite any back compatibility issues with the running version of drake.

Value

NULL

Details

Caution: garbage collection actually removes data so it is no longer recoverable with drake_history() or make(recover = TRUE). You cannot undo this operation. Use at your own risk.

Examples

if (FALSE) {
isolate_example("Quarantine side effects.", {
if (suppressWarnings(require("knitr"))) {
load_mtcars_example() # Get the code with drake_example("mtcars").
make(my_plan) # Run the project, build the targets.
# At this point, check the size of the '.drake/' cache folder.
# Clean without garbage collection.
clean(garbage_collection = FALSE)
# The '.drake/' cache folder is still about the same size.
drake_gc() # Do garbage collection on the cache.
# The '.drake/' cache folder should have gotten much smaller.
}
})
