It is assumed that you have read Sections 3.1–3.4 of R4DS and completed Preparation 3 prior to completing this activity.
In this activity, you will:
- Create boxplots and scatterplot visualizations using
{ggplot2}. - Combine multiple geometric layers in one visualization.
- Identify when to map an aesthetic to a feature of a dataset or set to a specific value.
Remember to take these steps slowly, help each other out, and get a hold of your instructor when you have questions or issues.
You may need your PAT that you created in Preparation 2. If you misplaced this token, you will need to create a new one prior to beginning these steps.
Remember to take these steps slowly, help each other out, and get a hold of your instructor when you have questions or issues.
- In this GitHub repo, click on the
Fork icon near the upper-right-hand corner. You should be taken
a copy of this repo that is in your GitHub account - your page title
should be {username}/activity02-ggplot2-intro, where{username}is replaced with your GitHub username. - Click on the green Code button.
- Verify that the drop-down identifies that you are using the HTTPS method (this is probably the default view; otherwise, select “HTTPS”).
- Click on the
icon to
copy the repo HTTPS information.
- Log in to the RStudio Server.
- Verify that you are in an RStudio session (it doesn’t matter if it is a previous Project session or a “vanilla” RStudio session).
- Create a new Project. You can do this by clicking on the
icon or through the menus (File > New Project…).
- In the New Project Wizard pop-up, select Version Control on the Create Project screen, then select Git on the Create Project from Version Control screen.
- On the Clone Git Repository screen, paste the HTTPS information
from (2) into the Repository URL dialog box. It should look like:
https://github.com/<username>/activity02-ggplot2-intro.git - The Project directory name dialog box should automatically
populate with your repository name, but sometimes Macs have an issue
with this (if so, click into this box and press the
command key on your keyboard).
It should look something like: activity02-ggplot2-intro - In the Create project as subdirectory of dialog box, click on Browse.
- In the Choose Directory pop-up, navigate to your class-level
folder (i.e., you were encouraged to create a folder named either
STA418orSTA518) You were also encouraged to create anactivitiesfolder within your class-level folder to help organize our materials. Once you have navigated to the folder you wish this repo to be located, click Choose. - Verify that the Create project as a directory of dialog box contains the folder location that you previously specified, then click on Create Project.
- You may be asked to login with your GitHub credentials on a Clone Repository pop-up window. Provide your GitHub username and PAT (not your GitHub password) if prompted.
- After a few seconds, your RStudio session will refresh and you should be in your newly created RStudio Project!
The activity02-ggplot2-intro.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.
YOU DID IT!
Take 5 minutes to write a reflection on what you feel confident in and what you need to spend some time better understanding. What is one thing you can do to help clarify your current misunderstandings?
Next: Activity 3 will cover the foundational syntax of programming in R.
