Bob: Please, please spend some time with an R tutorial or two before you post here. This list can help, but I think we assume that you have already made an effort to learn basic R on your own. Your question is about as basic as it gets, so it appears to me that you have not done this. There are many many R tutorials out there. Some suggestions, by no means comprehensive, can be found here: https://www.rstudio.com/online-learning/#r-programming
Others will no doubt respond, but you can answer it yourself after only a few minutes with most R tutorials.
