The R stands for reserve capacity. When the needle reaches the R, you only have the reserve limit of fuel. If your vehicle gets 25 miles per gallon and your reserve capacity is 2 gallons, then you have another 50 miles to go before you run out. It's a bit of a safe zone to let you know it's time to fuel up so you don't run out completely.
