Activity 7 - Joins!

It is assumed that you have read Chapter 13 from R4DS and completed the Join Data Sets Primer.

In this activity, you will:

  • Combine datasets that have similar structure using bind_*.
  • Join datasets that may have different structures using *_join.
  • Create new variables that are conditioned on another variable using case_when.
  • Visualize spatial data.

☑️ Task 1: The Workflow

Remember that more detailed directions can be found in Task 1 of Activity 4.

fork Fork this repo and clone it to a new RStudio Project

pause

Planned Pause Point: If you have any questions, contact your instructor or another group. We will complete this Activity during our next class session

☑️ Task 2: Complete the RMarkdown File

The activity07-joins.Rmd file contains the directions for this activity. For the rest of this class period, you will complete the RMarkdown document with your neighbor(s). Your instructor will be circling and be available to help when needed.

Note that each person is working in their own repo. We are not worrying about collaborating for the time being and instead will be working on being more comfortable with the workflow for working between RStudio and GitHub.

However, do not continue in this README document until you and your neighbor(s) have completed your .Rmd files.

☑️ Task 3: Reflection

Take 5 minutes and pick one or two things that are still unclear. What do you need to do to better understand these items?

Next: Activity 8 will explore three special variable types: strings, factors, and datetimes.
