Chapter 1 Welcome

Hello! This is a course taught by Dr. Julie Stewart Lowndes and Dr. Allison Horst at the RStudio Conference: January 27-28 in San Francisco, California.

This course is for Excel users who want to add or integrate R and RStudio into their existing data analysis toolkit. It is a friendly intro to becoming a modern R user, full of tidyverse, RMarkdown, GitHub, collaboration & reproducibility.

This book is written to be used as a reference, to teach, or as self-paced learning. And also, awesomely, it’s created with the same tools and practices we will be talking about: R and RStudio — specifically bookdown — and GitHub. It is being fine-tuned but the most recent version is always available:
