Go to the course GitHub organization: https://github.com/sta199-fa20-002.
If you see a pending invite at the top of the page, accept the invite to join the course invite. We’ll come back to GitHub later.
Let’s take a tour of R and RStudio. I’ll do a short demo, then give you a few minutes to try out yourself.
Go to https://vm-manage.oit.duke.edu/containers and log into the Docker container titled “RStudio - statistics application with Rmarkdown and knitr support”. This is where you’ll use RStudio during the semester.
Use R as a calculator by typing the following in the console.
3 * 5 + 10x <- 3
x + x^2x <- 1:10
x*7Go to the course organization on GitHub and find the repo with the prefix ae-02-.
Clone the repo and make a new project in RStudio.
You should see the files for the Flint Water Crisis analysis in the Files pane.
Configure git by running the following code in the console. Fill in your GitHub username and the email address associated with your GitHub account.
library(usethis)
use_git_config(user.name = "GitHub username", user.email="your email")Open the RMarkdown file ae02-flint.Rmd. We will use that for the next part of class.
Put your name for the author, then knit the document.
Select all of the updated files in the Git pane, click to commit and write the commit message “Updated author name”.
Click to push your changes.
If you refresh your repo on GitHub, you will see the updated files with your commit message.
Follow along with the instructions in app02-flint.Rmd. An html version of the file can be found here.
Once you have completed the activity, push your final changes to your GitHub repo! Make sure your repo is updated on GitHub, and that’s all you need to do to submit application exercises for participation.
