I am very new to using R so I apologize if this is a very straightforward question. I just imported a dataset from Excel that contains data on Bitcoin prices (daily price in $) and the corresponding dates. I have a total of 745 observations and 2 variables (Date and ClosingPrice). I tried using the PSY function from the psymonitor package (I'm trying to test for bubbles in Bitcoin) and got the following error in return:
" Error: Can't subset columns that don't exist.
x Locations 3, 4, 5, 6, 7, etc. don't exist.
There are only 2 columns. "
I have included a screenshot below (incase it helps).
