Delete metadata.

Delete the project metadata files from the local file system, the cloud, or both.

tar_meta_delete(
  meta = TRUE,
  progress = TRUE,
  process = TRUE,
  crew = TRUE,
  verbose = TRUE,
  delete = "all",
  script = targets::tar_config_get("script"),
  store = targets::tar_config_get("store")
)

Arguments

meta

Logical of length 1, whether to process the main metadata file at _targets/meta/meta.

progress

Logical of length 1, whether to process the progress file at _targets/meta/progress.

process

Logical of length 1, whether to process the process file at _targets/meta/process.

crew

Logical of length 1, whether to process the crew file at _targets/meta/crew. Only exists if running targets with crew.

verbose

Logical of length 1, whether to print informative console messages.

delete

Character of length 1, which location to delete the files. Choose "local" for local files, "cloud" for files on the cloud, or "all" to delete metadata files from both the local file system and the cloud.

script

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

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.
