I allready have R and RStudio installed!
In that case all you need to do is the following:
Make sure you have tidyverse
and readxl
installed:
install.packages("tidyverse")
install.packages("readxl")
Check that they are installed and work:
library(tidyverse)
library(readxl)
Download the example spreadsheet we are working with in this course:
Either using R
download.file("https://raw.githubusercontent.com/KUBDatalab/R-EDA/main/data/flightdata.xlsx",
destfile = "flightdata.xlsx", mode = "wb")
Or directly from this link
Make sure you can find the file again.
Detailed setup instructions
Where to install?
Please do NOT install R and RStudio on Onedrive or other clouddrives. R will work but you will not be able to install the extensions to R that you will need in this course!
R and RStudio are separate downloads and installations. R is the underlying statistical computing environment, but using R alone is no fun. RStudio is a graphical integrated development environment (IDE) that makes using R much easier and more interactive. You need to install R before you install RStudio. Once installed, because RStudio is an IDE, RStudio will run R in the background. You do not need to run it separately.
After installing both programs,
you will need to install the tidyverse
package from within RStudio. The
tidyverse
package is a powerful collection of data science tools within R
see the tidyverse
website for more details.
Follow the instructions below for your operating system, and then follow the
instructions to install tidyverse
.
Windows
If you already have R and RStudio installed
- Open RStudio, and click on “Help” > “Check for updates”. If a new version is available, quit RStudio, and download the latest version for RStudio.
- To check which version of R you are using, start RStudio and the first thing
that appears in the console indicates the version of R you are
running. Alternatively, you can type
sessionInfo()
, which will also display which version of R you are running. Go on the CRAN website and check whether a more recent version is available. If so, please download and install it. You can check here for more information on how to remove old versions from your system if you wish to do so.
If you don’t have R and RStudio installed
- Download R from the CRAN website.
- Run the
.exe
file that was just downloaded. - Go to the RStudio download page.
- The site will attempt to guess the correct version depending on your computer. If the guess is wrong, find the correct version at the bottom of the page
- Double click the file to install it.
- Once it’s installed, open RStudio to make sure it works and you don’t get any error messages.
Now return to the top of this page and finish the instructions under “I allready have R and RStudio installed!”

Linux
- Follow the instructions for your distribution
from CRAN, they provide information
to get the most recent version of R for common distributions. For most
distributions, you could use your package manager (e.g., for Debian/Ubuntu run
sudo apt-get install r-base
, and for Fedorasudo yum install R
), but we don’t recommend this approach as the versions provided by this approach are usually out of date. In any case, make sure you have at least R 3.3. - Go to the RStudio download page.
- The site will attempt to guess the correct version depending on your computer. If the guess is wrong, find the correct version at the bottom of the page

Online
The company behind RStudio offers a free cloudbased instance of RStudio at Posit Cloud. where you will be able to run R and RStudio in your browser. Sign up with your Google/Gmail account if you have one, or with any other email.
The free version of Posit Cloud places limitations on the number of projects you can work on, and the amount of memory and processing power you can access.
Due to the size of the dataset used in this workshop, Posit Cloud is not an alternative to installing R and Rstudio on you own computer.
