At this point, there are a large number of tasks that you could do with R Markdown:Ĭompile a single R Markdown document to a report in different formats, such as PDF, HTML, or Word.Ĭreate notebooks in which you can directly run code chunks interactively. During the past four years, it has steadily evolved into a relatively complete ecosystem for authoring documents, so it is a good time for us to provide a definitive guide to this ecosystem now. The latter renders Markdown to the output format you want (such as PDF, HTML, Word, and so on). The former executes the computer code embedded in Markdown, and converts R Markdown to Markdown. In a nutshell, R Markdown stands on the shoulders of knitr and Pandoc. Now we can write more types of elements with Markdown while still enjoying its simplicity. More importantly, the Markdown syntax was significantly enriched. Fortunately, John MacFarlane created a wonderful package named Pandoc ( ) to convert Markdown documents (and many other types of documents) to a large variety of output formats. For example, there was no syntax for tables, footnotes, math expressions, or citations. However, the original version of Markdown invented by John Gruber was often found overly simple and not suitable to write highly technical documents. The simplicity of Markdown clearly stands out among these document formats. Looking back over the five years, it seems to be fair to say that Markdown has become the most popular document format, which is what we expected. In fact, knitr supported several authoring languages from the beginning in addition to Markdown, including LaTeX, HTML, AsciiDoc, reStructuredText, and Textile. The idea was to embed code chunks (of R or other languages) in Markdown documents.
For Stata users this would be like the do-file, for SPSS users is like the syntax and for SAS users the SAS program. The R script is where you keep a record of your work. The document format “R Markdown” was first introduced in the knitr package ( Xie 2015, 2023b) in early 2012. The usual Rstudio screen has four windows: Console.
