About line 205 in learn.yaml, the instructions say this:
Output: "In this script, we've used a special chaining operator, %>%, which was originally introduced in the magrittr R package and has now become a key component of dplyr. You can pull up the related documentation with ?chain. The benefit of %>% is that it allows us to chain the function calls in a linear fashion. The code to the right of %>% operates on the result from the code to the left of %>%.\n\nOnce again, just try to understand the code, then type submit() to continue."
The help is actually found with ?magrittr .
If you want to find out more about the "chain" operator, click on the %>% operator which is described as "pipe".
