tar_helper_raw

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)

Examples

path <- tempfile()
tar_helper_raw(path, quote(x <- 1))
writeLines(readLines(path))

targets

Dynamic Function-Oriented 'Make'-Like Declarative Workflows
