When researching the documentation for str(), I noticed that it was part of the utils package. Why don’t I see the code loading utils?

Also, the lesson says to paste students %>% summarise(mean_score = mean(score)) into the code, but I had to type it by hand because Codecademy never lets me paste anything into it (the one exception being during the course, https://www.codecademy.com/learn/learn-how-to-code). Does anyone else have this problem?

This user has not encountered that copy-paste difficulty. Sometimes Ctrl-C / Ctrl-V works even if copy-paste with the mouse doesn’t.

While the results are exactly the same, students %>% summarise(mean_score = mean(score)) passes but summarise(students, mean_score = mean(score)) does not pass.

Some of us like putting arguments into the functions that use them, thanks.
