Assignment 6: Vector Operations

Now that you’ve been introduced to predicates, measures, and transformers in the sf package. You should be able complete a relatively simple workflow for a spatial analysis. We’ll build on this again with raster data (using terra) next week and then integrate both data models the week after that. By the end of this assignment you should be able to:

Use predicates and data manipulation tools from the dplyr package to subset data
Use transformers to create new geometries
Use measures to calculate new values based on the transformed geometries
Generate simple maps depicting the results of your calculation.

You’ll need to accept the link to access the questions.

Instructions

After you’ve joined the assignment repository, you should have this file (named Readme.md) inside of a R project named assignment-6-xx where xx is your github username (or initials).
Once you’ve verified that you’ve correctly cloned the assignment repository, create a new Quarto document. Name this file assignment-6-xxx.qmd and give it a title (like M Williamson Assignment 6). Make sure that you select the html output option (Quarto can do a lot of cool things, but the html format is the least-likely to cause you additional headaches). We’ll be using Quarto throughout the course so it’s worth checking out the other tutorials in the getting started section.
Copy the questions below into your document and change the color of their text.
Save the changes and make your first commit!
Answer the questions making sure save and commit at least 3 more times (having 4 commits is part of the assignment).
Render the document to html (you should now have at least 3 files in the repository: Readme.md, assignment-6-xx.qmd, and assignment-6-xx.html). Commit these changes and push them to the repository on GitHub. You should see the files there when you go to github.com.
