    hello, I need your help. I have been trying to conduct a t test in R, the code i entered is as follow: "t.test(Unit Price~Shipping Cost, data = SuperStoreUS_2015, var.equal=TRUE) Error: unexpected symbol in "t.test(Unit Price". i have done it many times on different computers, same result. I can't see what unexpected symbol R is talking about. Can you help?

    Beeeen trying to import a CSV file and I wondered why are the steps were not working. Turns out, I did not specify my file name by adding .CSV to it 😂 unnecessary thing to be stuck on but, I’m glad I finally got it. Took watching this video to see that. Thank you.
