This is an example targets repository for learning targets, as part of my course: A Gentle Introduction to {targets} and {geotargets}

It is currently still being developed. There is one folder per chapter, and each one is the same analysis at a later stage, working towards a full targets pipeline. The data is shared, in data/.

• ch1/01-flat-script.R: everything in one file. ch1/extensions/ has things you might want to try next.
• ch2/: the same analysis as named calls. 02-functions.R and analysis.R call the functions in ch2/R/, and toad-report.qmd reads what analysis.R writes.
• Chapter 3 is debugging, and changes no code.
• ch4/04-first-pipeline.R: the same calls, wrapped in tar_assign().
• ch5/05-deeper.R: file targets, a report, validation.
• ch6/06-branching.R: branching, then a controller.
• ch7/07-geotargets.R: rasters arrive. tar_terra_rast().
• ch8/08-production.R: what it looks like organised, with packages.R and section comments.

Chapters 4 to 8 are sketches, and do not run yet.

Some general conventions to follow:

• verbs in R/
• nouns in the plan
• one call per target
• piped |> tar_target()
• files as format = "file"
• writers return paths
