plan_to_code {drake}R Documentation

Turn a drake plan into a plain R script file. [Questioning]


code_to_plan(), plan_to_code(), and plan_to_notebook() together illustrate the relationships between drake plans, R scripts, and R Markdown documents. In the file generated by plan_to_code(), every target/command pair becomes a chunk of code. Targets are arranged in topological order so dependencies are available before their downstream targets. Please note:

  1. You are still responsible for loading your project's packages, imported functions, etc.

  2. Triggers disappear.


plan_to_code(plan, con = stdout())



Workflow plan data frame. See drake_plan() for details.


A file path or connection to write to.
