Swirl is a package for R that turns the console into an interactive way to learn R programming and data science concepts. It starts from basic R to much more in-depth and advanced topics. Users are able to learn new concepts and immediately put them into practice by answering questions. You are also given immediate feedback, which is very helpful for more difficult concepts. It is completely free and the instructions for how to get started can be found here: [swirlstats.com/students.html.](https://swirlstats.com/students.html.)

R is both a programming language and an environment that is mostly used for statistical computing, data analysis, and machine learning algorithms. R's library allows a wide variety of techniques linear and nonlinear modeling, classical statistical tests, time-series analysis, classification, clustering, and others. The capabilities of R can be extended through the use of R software packages, which are packages created by the R community that can be used to conduct specialized techniques.

Use "$ R" to launch r interpreter. Once launched, prompts will show up before of each line of code to write that look like ">". The output of any of your code will have the line of output in brackets . If it were the first line of output, a "[1]" would appear before the output.
