The modeled r-square between miles-per-gallon and engine horsepower is `r r.sq`. If the code chunk becomes too long and unwieldy to embed in your text, you can create an object from that code in a separate chunk of code then reference that object inline. The mean miles per gallon is `r round(mean(mtcars$mpg), 1)` mpg. To control the precision, you can wrap the output with round, The mean miles per gallon is 20.090625 mpg. The mean miles per gallon is `r mean(mtcars$mpg)` mpg. To include your code in your R markdown text you simply write r write your r code here. Another great reason to use R markdown is that we can also include our R code directly within our text. Then transcribe this value into your document as follows:Īn automated way to do this is to embed the code chunk directly into your text by wrapping it between `r (backtic followed by the letter r) and another backtick. Inline R code Up till now we’ve been writing and executing our R code in code chunks. If you want to generate a floating TOC, add toc_float: true. Make sure that the toc parameter is indented at least two spaces from the xxx_document header: To have the document automatically generate a table of contents add toc: true to the html_document or word_document header. The %d, %B and %y parameters specify the date format. Note the mix of single quotes and back ticks that wrap the inline code. The above chunk makes use of an inline code chunk that will be discussed later in this tutorial. For example, to add the current date, add:ĭate: '`r format(Sys.time(), "%d %B, %Y")`' The YAML header can take on several parameters. If you intend on creating a Word document, substitute html_document with word_document. Make sure that the html_document: default line is indented at least two spaces. At the very least, your R markdown document should contain the following YAML header sandwiched between two sets of -: The YAML header controls the look and feel of your document. With R Markdown, you can easily create reproducible data analysis reports, presentations, dashboards, interactive applications, books, dissertations, websites, and journal articles, while enjoying the simplicity of Markdown and the great power of.
