Installing R, RStudio, packages
You will do all of your work in this class with the open source (and free!) programming language R. You will use RStudio as the main program to access R. Think of R as an engine and RStudio as a car dashboard—R handles all the calculations and the actual statistics, while RStudio provides a nice interface for running R code.
Install R
First you need to install R itself (the engine).
If you have a WINDOWS, click here: Download R 4.2.1 for Windows
If you have a MAC, click here: Download R 4.2.1 for macOS
Double click on the downloaded file (check your
Downloadsfolder). Click yes through all the prompts to install like any other program.If you use macOS, download and install XQuartz. You do not need to do this on Windows.
Install RStudio
Next, you need to install RStudio, the nicer graphical user interface (GUI) for R (the dashboard). Once R and RStudio are both installed, you can ignore R and only use RStudio. RStudio will use R automatically and you won’t ever have to interact with R directly.
- If you have a WINDOWS, click here: Download RStudio for Windows
- If you have a MAC, click here: Download RStudio for macOS
- Double click on the downloaded file (check your
Downloadsfolder). Click yes through all the prompts to install like any other program.
Double click on RStudio to run it (check your applications folder or start menu).

Install packages
Most R packages are easy to install with RStudio. Select the packages panel, click on “Install,” type the name of the package you want to install, and press enter. R will download the package from the web, so make sure you are connected to wifi when you do it.
A less tedious way to do this is via the console or in your script (just make sure to delete afterwards!), by running the following code:
install.packages("name_of_package")Install {juanr} (and other packages from Github)
Some packages, like {juanr} cannot be installed using install.packages() because they are hosted on Github. To install {juanr}, you will first need to install {remotes} and then use install_github(), like so:
install.packages("remotes")
remotes::install_github("hail2thief/juanr")
