tar_invalidate: Invalidate targets and global objects in the metadata.

Description Usage Arguments Details See Also Examples

View source: R/tar_invalidate.R

Description

Delete the metadata of records in _targets/meta/meta but keep the return values of targets in _targets/objects/.

Usage

1
tar_invalidate(names, store = targets::tar_config_get("store"))

Arguments

names

Names of the targets to remove from the metadata list. 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 invalidated. For patterns no longer in the metadata, branches are left alone.
