The targets package is a pipeline toolkit that brings together function-oriented programming and Make-like declarative pipelines for Statistics and data science in R. It implements a pipeline as collection of interconnected tasks, analyzes the dependency relationships among these tasks, skips steps that are already up to date, runs the necessary computations with optional parallel workers, abstracts files as R objects, and provides tangible evidence that the results match the underlying code and data. The methodology in this package borrows from GNU Make by Richard Stallman (2015, ISBN:978-9881443519) and drake by Will Landau (2018) (doi:10.21105/joss.00550).
