tar_exist_objects: Check if local output data exists for one or more targets.

In wlandau/targets: Dynamic Function-Oriented 'Make'-Like Declarative Pipelines

Check if local output data exists for one or more targets.

Description

Check if output target data exists in either ⁠_targets/objects/⁠ or the cloud for one or more targets.

Usage

tar_exist_objects(
  names,
  cloud = TRUE,
  store = targets::tar_config_get("store")
)

Arguments

names	Character vector of target names. Not tidyselect-compatible.
cloud	Logical of length 1, whether to include cloud targets in the output (e.g. tar_target(..., repository = "aws")).
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

If a target has no metadata or if the repository argument of tar_target() was set to "local", then the ⁠_targets/objects/⁠ folder is checked. Otherwise, if there is metadata and repsitory is not "local", then tar_exist_objects() checks the cloud repository selected.

Value

Logical of length length(names), whether each given target has an existing file in either ⁠_targets/objects/⁠ or the cloud.
