targets-demo

This repo is intended as a minimal demo of using the targets R package for workflow management using data from the palmerpenguins package.

Instructions

1. Explore the files in data/ and R/
2. Explore the workflow definition in _targets.R
3. Load the targets package with library(targets)
4. View the dependency graph with tar_visnetwork()
5. Run the workflow with tar_make() and then view the dependency graph again
6. In R/fit_models.R, change the response variable from flipper_length_mm to bill_length_mm and run tar_visnetwork() again
7. Run tar_make() and notice which steps are skipped

Check out the manual for instructions on how to run the pipeline.
