Check on Sakai > Resources > Lab Teams to see your team assignment. This will be your team for labs and the final project. Before you get started on the lab itself, we’ll take a few minutes to help you develop a plan for working as a team.
In this lab we will work with the data from this article to recreate some of their visualizations as well as explore new questions.
The learning goals of this lab are to practice working as a team, and also to reinforce skills learned regarding linear regression with a single continuous predictor.
Each step in the process will be outlined - pay attention to the directions carefully, or else you may run into a merge conflict (uh oh!). In next week’s lab, we will learn how to resolve merge conflicts, but let’s go one step at a time to work as a team first.
Not only will your grade be based on answers to the lab assignment, but also on whether each team member was able to successfull commit and push their assigned question. Watch out for all of the steps below (especially “when to pull”).
A repository has already been created for you and your teammates. Everyone in your team has access to the same repo.
Go to the course organization on GitHub.
In addition to your private individual repositories, you should now see a repo named lab-01-[team-number]. Go to that repository.
ONE MEMBER of the team should edit the README file directly in your web browser (not in RStudio) by clicking on the Edit icon in your repository. Edit in the two-hour block outside of class, your communication method, and your team name into the README file. Commit this change in your web browser.
Each person on the team should now clone the repository and open a new project in RStudio. Do not make any changes to the .Rmd file until the instructions tell you do to so.
Assign each person on your team a number 1 through 4. For teams of three, Member 1 can take on the role of Member 4.
The following exercises must be done in order.
Only one person should type in the .Rmd file and push updates at a time.
When it is not your turn to type, you should still share ideas and contribute to the team’s discussion.
Team Member 1: Change the
author to your team name and include each team member’s name in the
author field of the YAML in the following format.
Team Name: Member 1, Member 2, Member 3, Member 4.
For instance:
The Fantastic Four: Mr. Fantastic, Invisible Woman, Human Torch, The Thing
We’ll use the tidyverse package for this analysis. Run the following code to load this package.
library(tidyverse)The dataset for this assignment can be found as a csv file in the
data folder of your repository. You can read it in using
the following code (fill in the blank, giving the dataset a meaningful
name in R).
____ <- read_csv("data/____.csv")Team Member 1: Type the team’s responses to exercise 1 (everyone else, hands off!).
Team Member 1: Knit, commit and push your changes to GitHub with an appropriate commit message again. Make sure to commit and push all changed files so that your Git pane is cleared up afterwards.
All other team members: Pull to get the updated documents GitHub. Click on the .Rmd file, and you should see the responses to exercises 1 and 2.
Team Member 2: It’s your turn! Type the team’s response to exercise 2 below (everyone else, hands off!):
Team Member 2: Knit, commit and push your changes to GitHub with an appropriate commit message again. Make sure to commit and push all changed files so that your Git pane is cleared up afterwards.
All other team members: Pull to get the updated documents GitHub. Click on the .Rmd file, and you should see the responses to exercise 2.
Team Member 3: It’s your turn! Type the team’s response to exercise 3.
Team Member 3: Knit, commit and push your changes to GitHub with an appropriate commit message again. Make sure to commit and push all changed files so that your Git pane is cleared up afterwards.
All other team members: Pull to get the updated documents GitHub. Click on the .Rmd file, and you should see the responses to exercise 3.
Team Member 4 (or back to Team Member 1): It’s your turn! Type the team’s response to the last exercise below.
Team Member 4: Knit, commit and push your changes to GitHub with an appropriate commit message again. Make sure to commit and push all changed files so that your Git pane is cleared up afterwards.
All other team members: Pull to get the updated documents GitHub. Click on the .Rmd file, and you should see the team’s completed lab.
Team Member 2: Make any edits as needed. Then knit, commit, and push the updated documents to GitHub if you made any changes.
All other team members: click to pull the finalized document.
Team Member 3: Upload the team’s PDF to Gradescope. Be sure to include every team member’s name in the Gradescope submission, and then “associate” the answer to each of the exercises. If any answer spans multiple pages, then mark all pages.
There should only be one submission per team on Gradescope.
