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

Source: R/tar_exist_objects.R
tar_exist_objects.Rd

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.

Value

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

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.
