tar_exist_script: Check if the target script file exists.

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

Check if the target script file exists.

Description

Check if the target script file exists for the current project. The target script is ⁠_targets.R⁠ by default, but the path can be configured for the current project using tar_config_set().

Usage

tar_exist_script(script = targets::tar_config_get("script"))

Arguments

script

Character of length 1, path to the target script file. Defaults to tar_config_get("script"), which in turn defaults to ⁠_targets.R⁠. When you set this argument, the value of tar_config_get("script") is temporarily changed for the current function call. See tar_script(), tar_config_get(), and tar_config_set() for details about the target script file and how to set it persistently for a project.

Value

Logical of length 1, whether the current project's metadata exists.
