1 Introduction

The litteR-package requires a recent installation of the R-environment (R version 3.6.1 (2019-07-05) or later). In addition, MS-Windows users also need to install RStudio, an integrated development environment (IDE) for R.

The aim of this manual is to help people with no, or only a limited experience with R and RStudio to

  1. install the R-environment;
  2. install RStudio;
  3. install and update the litteR-package (and its dependencies).

Although this manual primarily focuses on MS-Windows users, users of other operating systems may also find these instructions useful.

2 Installation of R

The latest version of R can be downloaded from the Comprehensive R Archive Network (CRAN) website as follows:

  1. Navigate in a web-browser to https://cran.r-project.org;
  2. Select the R-version for your operating system, e.g., Download R for Windows;
  3. Select ‘base’;
  4. Select Download R x.y.z (where x.y.z. is the version number, e.g., 3.6.1);
  5. Double click on the downloaded file and follow the installation instructions on the screen. In case of doubt, simply select the default/recommended settings.

The latest version of RStudio can be downloaded from the RStudio website: https://rstudio.com:

  3. Click on the link ‘RStudio x.y.z - Windows 10/8/7 (64-bit)’ to download the MS-Windows version of RStudio (or click another link that matches your operating system). Again, x.y.z. is the version number;
  4. Double click on the downloaded file and follow the installation instructions on the screen. In case of doubt, simply select the default/recommended settings.
