Lab 4

Overview

Because we will have a visitor today, this is a very short lab. The purpose of this lab is to help you to use color to your advantage. You will be asked to use a variety of color palettes, and use color for its three main purposes: (a) distinguish groups from each other, (b) represent data values, and (c) highlight particular data points. Lab PS-3 will build on this lab that will also add an exporation of themes.

Data

• We’ll be working with the honey production data from #tidytuesday. The #tidytuesday repo contains the full data, but we’ll work with just the cleaned up version, using the honeyproduction.csv file, which is posted in the data folder in the course repo.

Wrangle Data

1. Visualize the total production of honey across years by state Use color to highlight the west coast (Washington, Oregon, and California) with a different color used for each west coast state.

• Hint 1: I’m not asking for a specific kind of plot, just one that does the preceding. But if you’re trying to visualize change over time, a bar chart is likely not going to be the best choice.
• Hint 2: To get each state to be a different color you should either map state to color (for your layer that adds the west coast colors) or use the gghighlight package.

2. Reproduce the plot according three different kinds of color blindness, as well as a desaturated version.

3. Reproduce the plot using a color blind safe palette.

Finishing up
