Although this part now links out to external resources, if you’re working through this material on your own, let this be a nudge to pause around here and think about your workflow. I give you permission to spend some time and energy sorting this out! It can be as or more important than learning a new R function or package. The experts don’t talk about this much, because they’ve already got a workflow and it’s something they do almost without thinking.

Working through subsequent material in R Markdown documents, possibly using Git and GitHub to track and share your progress, is a great idea and will leave you more prepared for your future data analysis projects. Typing individual lines of R code is but a small part of data analysis and it pays off to think holistically about your workflow.
