tar_helper_raw: Write a helper R script (raw version).

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

Write a helper R script (raw version).

Description

Write a helper R script for a targets pipeline. Could be supporting functions or the target script file (default: ⁠_targets.R⁠) itself.

Usage

tar_helper_raw(path = NULL, code = NULL)

Arguments

path	Character of length 1, path to write (or overwrite) code. If the parent directory does not exist, tar_helper_raw() creates it.
code	Expression object. tar_helper_raw() deparses and writes this code to a file at path, overwriting it if the file already exists.

Details

tar_helper_raw() is a specialized version of tar_script() with flexible paths and tidy evaluation. It is like tar_helper() except that code is an "evaluated" argument rather than a quoted one.

Value

NULL (invisibly)
