There are a plethora of options that become available to us when using code chunks so this tends to be the more complex part of R Markdown documents. There are two main ways to process code with Knitr in R Markdown documents:įirst, we’re going to talk about code chunks more substantial portions of code into our narrative such as figures and plots. It utilizes Literate Programming to make research more reproducible. It’s specifically a package that allows the integration of R code into the html, word, pdf, or LaTex document you have specified as your output for R Markdown. What is Knitr?īut what is Knitr? Knitr is the engine in RStudio which creates the “dynamic” part of R Markdown reports. Knitr runs the lines of code for a plot in a code chunk, joins it to the markdown text portions, and rmarkdown outputs that as an html document. Secondly, rmarkdown processes the code output and displays it in the document format of our choice - i.e. Instead of R Markdown’s rendering system processing the markdown styling into the final output, Code chunks are sent to a preceding stage of processing by Knitr, which “knits” the code output and text together. How do you signal to R the difference between code and text when you’re not using code commments (#)? That’s where “Code Chunks” come into play (Yes that’s RStudio’s technical name for them). Instead of priortizing the code and making you comment out (#) text, they priortize text and force you to specially signal the code portions. R Markdown flips around the defaults of code and text in the documents. We’ve learned about the text-formatting options of R Markdown, now let’s dive into the code portion of R Markdown documents.
