R vignettes, blog posts and teaching materials are typically standard web pages generated with R Markdown. DataCamp has developed a framework to make this static content interactive: R code chunks are converted into an R-session backed editor so readers can experiment. This talk will explain the inner workings of the technology, as well as a the tutorial R package that makes the transition to interactive web pages seamless. Some hands-on examples will showcase the remarkable ease with which you can convert R Markdown documents, vignettes and Jekyll-powered blogs into interactive R playgrounds.
