 The working directory can changed but when working with Quarto this only influences individual code chunks (which is mentioned in a warning when executing the code below). However it is really useful when working with raw R scripts which are taught in the upcoming R for data science (R part 2) course.

 Often we will work with large datasets that already exist in i.e. an excel sheet or a tab separated file (.tsv). We can easily load that data into R, either with the read_excel function or by clicking on 'Import Dataset' in the Environment tab (right). We can also load data in via a command. Let's do this now. Navigate to the data from your working directory. Use the tap-button to check what your options are.
