In discovr: Interactive Tutorials and Data for "Discovering Statistics Using R and RStudio"

To work outside of this tutorial you need to download the following data files:

• puppy_rct.csv
• hangover.csv

Set up an r rstudio() project in the way that I recommend in this video, and save the data files to the folder within your project called [data]{.alt}. To read in the first datafile place this code in the first code chunk in your r quarto() document:

puptreat_tib <- here::here("data/puppy_rct.csv") |>
  read_csv() |>
  mutate(
    dose = as_factor(dose) |> fct_relevel("No puppies", "15 mins", "30 mins")
  )

This code reads in the data, converts the variable dose to a factor (categorical variable) using as_factor() and sets the order of factor levels using fct_releval(). We can use very similar code

For the hangover data use this code:

cure_tib <- here::here("data/hangover.csv") |>
  read_csv() |>
  mutate(
    drink = as_factor(drink) |> fct_relevel("Water", "Lucozade", "Cola")
  )

This code reads in the data, converts the variable drink to a factor (categorical variable) and sets the order of the factor levels to match this tutorial.
