R code for the target script file _targets.R. library(targets) is automatically written at the top.

run

R code to inspect and run the pipeline.

Details

The best way to get help with an issue is to create a reproducible example of the problem and post it to https://github.com/ropensci/targets/discussions tar_reprex() facilitates this process. It is like reprex::reprex({targets::tar_script(...); tar_make()}), but more convenient.
