Yes. Have you gone through any R tutorials, yet? There are many good ones on the web, some of which are listed here: https://www.rstudio.com/online-learning/ See also the "Intro to R" tutorial that ships with R.
Spending a little time with these will help you understand R's capabilities and, of course, learn how to use them.
