Directory path to the support scripts of the current target script

Identify the directory path to the support scripts of the current target script of the pipeline currently running.

tar_path_script_support()

Value

Character, directory path to the target script of the pipeline currently running. If called outside of the pipeline currently running, tar_path_script() returns tar_config_get("script").

Details

A target script (default: _targets.R) comes with support scripts if it is written by Target Markdown. These support scripts usually live in a folder called _targets_r/, but the path may vary from case to case. The tar_path_scipt_support() returns the path to the folder with the support scripts.
