I need an R programmer

Hi! I am trying to do a matched pair t test to compare the prices of 30 identical products at Target and Walmart. Additionally, I need a histogram of the prices at Walmart and one of the prices at target, along with a box plot that compares the prices at both chains. It would be awesome if you could also provide IQR. I have all the data, I just cannot use R for the life of me. This would definitely be very quick and easy, I just literally cannot figure this software out.
