Create a working directory Usually, people want to keep the folder structure on their computers tidy, so that they and their co-workers understand, which documents and data were used for a particular project – even if that project was finished months ago. This should also be the case when you work with R. Therefore, I recommend to create a new folder for every new project, which becomes the so-called working directory.
For this introduction I recommend to install two software packages on your system:
R: The software, which does all the calculations. RStudio: The working environment, where all the code will be developed. Note that the instructions of this section were written for a standard installation on a private computer. If you work on a corporate machine, the installation could be different due to different IT requirements of your company.
