I am new to R so learning this is very difficult for me. I have a data set that has a number of variables that pertain to football teams. Some of these variables are: number of wins, average attendance, % conversion on 4th down, the year. I need to derive the mean number of wins for "Ohio State" in the block 2000-2016. Any and all help is appreciated. I attached a screenshot just to give you an idea of what I am working with.
