Hi there
When I try to answer the below question, no matter what I input (1 or 2), it always says "argument is of length zero" and the question shows up again.

I'm using Mac, R studio and R version 3.4.2. I met this problem for both these two parts:
1: Getting and Cleaning Data Grouping and Chaining with dplyr
2: Getting and Cleaning Data Manipulating Data with dplyr
But I haven't finished the third and forth part in Getting and Cleaning Data.
