In order to carry out a data analysis, the data must first be loaded into R. In the raw form (Supplementary Material: bfp_data.txt), the data are in the form of a text file. The first column of the file shows the group membership, while the second column contains the respective fat content. The columns are separated by a comma and a dot is used as decimal separator, following international conventions. To load the data into R, the read_csv() function from the readr package is used. First, however, the current working directory of R must be set to the corresponding folder under which the file is stored. The function setwd() (short for set working directory) is used for this. Since path specifications in R are always determined relative to the working directory, this step makes further work easier since no long file paths have to be specified.
