Mapping data to graphics

Lesson for Monday, June 10, 2024–Friday, June 14, 2024

Part 1: Data visualization with {ggplot2}

For the first part of this week’s lesson, you need to work through Posit’s introductory primers for {ggplot2}. You’ll do these in your browser and type code and see results there.

It seems like there are a lot, but they’re short and go fairly quickly (especially as you get the hang of the ggplot() syntax). Complete these:

• Visualize Data
  • Exploratory data analysis
  • Bar Charts
  • Histograms
  • Boxplots and counts
  • Scatterplots
  • Line plots
  • Overplotting and big Data
  • Customize your plots

Part 2: Reshaping data with {tidyr}

For the last part of this week’s lesson, you’ll work through just one primer to learn how to use the {tidyr} package to reshape data from wide to long and back to wide.

Complete this:

• Tidy Your Data
  • Reshape Data
