Out.width and out.height: The output size of R plots in the output document. You can also specify the two options together in a single chunk option fig.dim, e.g., fig.dim = c(6, 4) means fig.width = 6 and fig.height = 4.

R plots in code chunks are first recorded via a graphical device in knitr, and then written out to files. Caching can be handy but also tricky sometimes.įig.width and fig.height: The (graphical device) size of R plots in inches. However, I want to honestly remind you of the two hard problems in computer science (via Phil Karlton): naming things, and cache invalidation. If caching is enabled, the same code chunk will not be evaluated the next time the document is compiled (if the code chunk was not modified), which can save you time. When you are trying to set echo = FALSE, results = 'hide', warning = FALSE, and message = FALSE, chances are you simply mean a single option include = FALSE instead of suppressing different types of text output individually.Ĭache: Whether to enable caching. When include = FALSE, this whole code chunk is excluded in the output, but note that it will still be evaluated if eval = TRUE. Code folding allows you to easily show and hide blocks of code to make it easier to navigate your source file. Include: Whether to include anything from a code chunk in the output document.
Similarly, when warning = FALSE or message = FALSE, these messages will be shown in the R console.

Note that if you set error = FALSE, rmarkdown::render() will halt on error in a code chunk, and the error will be displayed in the R console. 1 Installation 1.1 Use a Pandoc version not bundled with the RStudio IDE 1.2 Install LaTeX (TinyTeX) for PDF reports 1.3 Install missing LaTeX packages 2 Conceptual Overview 2.1 What happens when we render 2.2 R Markdown anatomy 2.3 What can we change to change the results 3 Basics 3. Warning, message, and error: Whether to show warnings, messages, and errors in the output document. The default collapse = FALSE means R expressions and their text output are separated into different blocks. When this feature is enabled in the qmd YAML, the person viewing the document can hide/unhide code chunks. githubdocument () gains mathmethod 'default' and defaults to it. The latter will be removed eventually from this package. Please use tufte::tuftehandout () instead of rmarkdown::tuftehandout (). This is mostly cosmetic: collapse = TRUE makes the output more compact, since the R source code and its text output are displayed in a single output block. Code-folding One of the neat new features is code-folding. Its codebase was moved to the tufte package in 2016, and this function was marked as deprecated in 2021. By default, text output will be wrapped in verbatim elements (typically plain code blocks).Ĭollapse: Whether to merge text output and source code into a single code block in the output. Results: When set to 'hide', text output will be hidden when set to 'asis', text output is written “as-is”, e.g., you can write out raw Markdown text from R code (like cat('**Markdown** is cool.\n')). option class.source fold-show, e.g., - title: Hide all code blocks. We list a subset of them below:Įcho: Whether to echo the source code in the output document (someone may not prefer reading your smart source code but only results). choose to unfold all code blocks initially (so readers can choose to fold. There are a large number of chunk options in knitr documented at. 19.7 Output arguments for render functions.16.5.4 Create a widget without an R package.
