# Reproducible computation at scale in R with [`targets`](https://github.com/ropensci/targets)
[](https://rstudio.cloud/project/1699460)
Data science can be slow. A single round of statistical computation can take several minutes, hours, or even days to complete. The [`targets`](https://github.com/ropensci/targets) R package keeps results up to date and reproducible while minimizing the number of expensive tasks that actually run. [`targets`](https://github.com/ropensci/targets) arranges the steps of your pipeline, skips costly runtime for steps that are already up to date, runs the rest with optional implicit parallel computing, abstracts files as R objects, and shows tangible evidence that the output matches the underlying code and data. In other words, the package saves time while increasing your ability to trust the results. This hands-on workshop teaches targets using a realistic case study from , to an 2018 RStudio AI Blog post by Matt Dancho: . Participants gradually build up a [`targets`](https://github.com/ropensci/targets)-powered machine learning pipeline through guided hands-on R programming exercises.
