List targets whose progress is "errored".
tar_errored(names = NULL, store = targets::tar_config_get("store"))Optional, names of the targets. If supplied, the
output is restricted to the selected targets.
The object supplied to names should be NULL or a
tidyselect expression like any_of() or starts_with()
from tidyselect itself, or tar_described_as() to select target names
based on their descriptions.
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.
A character vector of errored targets.
Several functions like tar_make(), tar_read(), tar_load(),
tar_meta(), and tar_progress() read or modify
the local data store of the pipeline.
The local data store is in flux while a pipeline is running,
and depending on how distributed computing or cloud computing is set up,
not all targets can even reach it. So please do not call these
functions from inside a target as part of a running
pipeline. The only exception is literate programming
target factories in the tarchetypes package such as tar_render()
and tar_quarto().

tar_dispatched(),
