R is an elegant and comprehensive statistical and graphical programming language. Unfortunately, it can also have a steep learning curve. I created this website for both current R users, and experienced users of other statistical packages (e.g., SAS, SPSS, Stata) who would like to transition to R. My goal is to help you quickly access this language in your work.
I assume that you are already familiar with the statistical methods covered and instead provide you with a roadmap and the code necessary to get started quickly, and orient yourself for future learning. I designed this web site to be an easily accessible reference. Look at the sitemap to get an overview.
If you prefer an online interactive environment to learn R, this free R tutorial by DataCamp is a great way to get started. If you're already somewhat advanced and interested in machine learning, try this Kaggle tutorial on who survived the Titanic.
A link to the new resource The R Graph Gallery has been added.
A number of new sections have been added. These include:
If you currently use another statistical package, why learn R?
R is available for Linux, MacOS, and Windows (95 or later) platforms. Software can be downloaded from one of the Comprehensive R Archive Network (CRAN) mirror sites.
