Initialize a Git repository for a targets data store.


  store = targets::tar_config_get("store"),
  stash_gitignore = TRUE,
  git_lfs = TRUE,
  verbose = TRUE



Character of length 1, path to the data store of the pipeline. If NULL, the store setting is left unchanged in the YAML configuration file (default: _targets.yaml). Usually, the data store lives at _targets. Set store to a custom directory to specify a path other than _targets/. The path need not exist before the pipeline begins, and it need not end with "_targets", but it must be writeable. For optimal performance, choose a storage location with fast read/write access. If the argument NULL, the setting is not modified. Use tar_config_unset() to delete a setting.


Logical of length 1, whether to temporarily stash the .gitignore file of the data store. See the "Stashing .gitignore" section for details.


Logical, whether to automatically opt into Git LFS to track large files in _targets/objects more efficiently. If TRUE and Git LFS is installed, it should work automatically. If FALSE, you can always opt in later by running git lfs track objects inside the data store.


Logical of length 1, whether to print messages to the R console.


NULL (invisibly).


tar_git_init() also writes a .gitattributes file to the store to automatically track target output date with git-lfs if it is installed on your system.

Stashing .gitignore

The targets package writes a .gitignore file to new data stores in order to prevent accidental commits to the code Git repository. Unfortunately, for gittargets, this automatic .gitignore file interferes with proper data versioning. So by default, gittargets temporarily stashes it to a hidden file called .gittargets_gitignore inside the data store. If your R program crashes while the stash is active, you can simply move it manually back to .gitignore or run tar_git_status_data() to restore the stash automatically if no .gitignore already exists.
