Description

R has become one of the main tools in the data science pipeline for analysis and reporting, but many users don’t know what to do when their data gets big. If the data can’t be stored in memory, can we still use R?

Aimee Gott, Mark Sellors, and Richard Pugh explore techniques for optimizing your workflow in R when working with big data, including how to efficiently extract data from a database, techniques for visualization and analysis, and how all of this can be incorporated into a single, reproducible report, directly from R.

Aimee, Mark, and Richard start with an introduction to the manipulation functionality of dplyr for in-memory data before explaining how to use the package to work directly on the database. They look at how to connect to a database and get data into R without needing to write SQL, with a focus on best practices. After getting comfortable with getting subsets of the data from the database, Aimee, Mark, and Richard demonstrate how to use summaries of the data to generate graphics and perform simple analysis and prototyping before bringing it all together in the form of reproducible reporting with RMarkdown. Aimee, Mark, and Richard introduce how these techniques can be brought together in a single document.
