drake (version 7.5.2)

plan_to_notebook: Turn a drake workflow plan data frame into an R notebook,

Description

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.

Usage

plan_to_notebook(plan, con)

Arguments

plan

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

con

A file path or connection to write to.
