Delete locally stored target return values.

Source: R/tar_delete.R

Delete the return values of targets in _targets/objects/. but keep the records in _targets/meta/meta. Dynamic files and cloud data (e.g. format = "file" and format = "aws_parquet") are not deleted.

tar_delete(names, store = targets::tar_config_get("store"))

Arguments

names

Names of the targets to remove from _targets/objects/. You can supply symbols or tidyselect helpers like all_of() and starts_with().
store

Character of length 1, path to the targets data store. Defaults to tar_config_get("store"), which in turn defaults to _targets/. When you set this argument, the value of tar_config_get("store") is temporarily changed for the current function call. See tar_config_get() and tar_config_set() for details about how to set the data store path persistently for a project.

Details

For patterns recorded in the metadata, all the branches will be deleted. For patterns no longer in the metadata, branches are left alone.

Examples

if (identical(Sys.getenv("TAR_EXAMPLES"), "true")) {
tar_dir({ # tar_dir() runs code from a temporary directory.
tar_script({
  list(
    tar_target(y1, 1 + 1),
    tar_target(y2, 1 + 1),
    tar_target(z, y1 + y2)
  )
}, ask = FALSE)
tar_make()
tar_delete(starts_with("y")) # Only deletes y1 and y2.
tar_make() # y1 and y2 rebuild but return same values, so z is up to date.
})
