Invalidate targets and global objects in the metadata.
Delete the metadata of records in _targets/meta/meta
but keep the return values of targets in _targets/objects/.
tar_invalidate(names, store = targets::tar_config_get("store"))names |
Names of the targets to remove from the metadata list.
You can supply symbols

This function forces one or more targets to rerun
on the next tar_make(), regardless of the cues and regardless
of how those targets are stored. After tar_invalidate(),
you will still be able to locate the data files with tar_path()
and manually salvage them in an emergency.
However, tar_load() and tar_read() will not be able to
read the data into R, and subsequent calls to tar_make()
will attempt to rerun those targets.
For patterns recorded in the metadata, all the branches
will be invalidated. For patterns no longer in the metadata,
branches are left alone.
Other clean:
tar_delete(),
tar_destroy(),
tar_prune()
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_invalidate(starts_with("y")) # Only invalidates y1 and y2.
tar_make() # y1 and y2 rerun but return same values, so z is up to date.
