Knitr

Knitr is a tool that helps you write your own computer programs and make them look pretty. Imagine you want to write a recipe for cookies. Knitr would help you write the recipe and then make it look nice and easy to read by adding pretty pictures and formatting the text in a way that makes it easy to follow. Knitr does the same thing but with computer programs. You write your program and then knitr helps convert it into a pretty document that you can easily read and understand. It makes things easier because you don't have to worry about the technical details of formatting your code, knitr does it for you!
