Clif was saying that he has a hard time explaining how to use the yts data (as it is complicated) and thinks it might be better to not use it

I wonder if we could just use length() or nrow() instead of showing n_distinct() https://jhudatascience.org/intro_to_r/modules/Data_Summarization/Data_Summarization.html#28

we show that later: https://jhudatascience.org/intro_to_r/modules/Data_Summarization/Data_Summarization.html#46

and people are used to length() from earlier lectures like basic R
