Dedicated classes

You might have noticed that the fread() function produces data frames that look slightly different when you print them out. That's because another class named data.table is assigned to the resulting data frames. The printout of such data.table objects is different. Does something similar happen with the data frames generated by readr?

In your current working directory, we prepared the potatoes.txt file. The packages data.table and readr are both loaded, so you can experiment straight away.

Which of the following statements is true?
