Setup Guide

In order to be able to successfully run the notebooks and solve the exercises, make sure that you have the right environment set up.

R Version

These notebooks were developed using R 4.4.2, so ideally you should use the same version. You can check your current R version by running R --version in your terminal. If you have the same R version, you can skip the rest of this section.

A convenient way to simultaneously maintain different versions of R and to easily switch between them is to use rig, the R installation manager. It’s documentation contains instructions on how to install it on Windows, macOS, and Linux.

After having installed rig, you can install R 4.4.2 and make it the default by running the following command in your terminal:

rig add 4.4.2
rig default 4.4.2

Verify that the R version is 4.4.2 by running R --version in your terminal.

Libraries

For managing libraries, we use the renv package. If you don’t have renv installed, you can install it by running the following command:

install.packages("renv")

Next, initialize the renv environment by running the following command:

renv::init()

Finally, restore the renv environment by running the following command. This might take some time as it downloads all the required libraries.

renv::restore()

To be able to use the torch package, you need to also run this additional command:

torch::install_torch()

If this completes successfully, you are ready to go! 🚀

To optionally check whether you have GPU support installed (this is not necessary for the exercises), run the following command:

torch::cuda_is_available()
