This repo is dormant and will not developed further. With the advent of targets, drake has largely been superceded. Similar examples of targets can be found here: https://docs.ropensci.org/targets/#example-projects.

Install dependencies

remotes::install_deps(dependencies = TRUE, build = FALSE)

The goal of drake-example is to provide a template repo for using the drake package for R workflows. The repo is also tries to utilize R compendiums to manage dependencies and enables the suite package management tools. Here is the current directory of files for this type of project:

File Structures

fs::dir_tree()

Data

Fake data are created and stored in the data-raw directory. Here we are using the starwars data from the dplyr package.

Workflows

• Store re-useable functions in the R/ directories. devtools::load_all() makes them available during your R session like a package.
• Write analysis code in the code/ directory as normal R code.
• Use drake::code_to_plan() to bring those R scripts into your drake plan as targets. The plan and the targets are stored in _drake.R. For many of its processes, drake will automatically look for that _drake.R file.
• The exec_drake.R and the DESCRIPTION files are the main control files for the project. The most important element of this script is the drake::make() or drake::r_make functions. This file also sources all other required files.
