Summarizing
- Counts
- Summary functions
Pivoting Data
Joining Tables
Practice

Note 3.1

Since I already know quite a bit about this topic, I skipped it. There are, therefore, no notes on it.

But I have two remarks:

I am going to use the native pipe, provided with R 4.1.0. This are important differences to the {magrittr} pipe. See
- Hadley Wickham in the Tidyverse (“Differences between the base R and magrittr pipes”),
- Kathie Press (“Replacing the Magrittr Pipe With the Native R Pipe”)
- Geek for Geeks (“What are the differences between R’s native pipe |> and the {magrittr} pipe %>%?”)
- Isabella Velásquez (“Understanding the native R pipe |>”)
- StackOverflow (“What are the differences between R’s native pipe |> and the {magrittr} pipe %>%?”)
- Yihui Xie (“Substitute the magrittr Pipe %>% with R’s Native Pipe Operator |>”)
- R Bloggers (The new R pipe)
- Statistik Dresden (“R 4.1.0: Base R Pipe! |>”) in German
dplyr::transmute() is superseded because you can perform the same job with mutate(.keep = "none").
