In fact, metadata is just a convenient way to invoke functions that implement output formats. Output formats need not be specified in metadata. Using an _output.yml file is a good way to share output settings across multiple R Markdown files in the same directory. You can also define output formats externally in a file named _output.yml located in the same directory as the R Markdown source file. You can also render all formats defined in the file with: render("input.Rmd", "all") Shared Output Formats If no explicit format name is passed to render then the first one defined will be used. For example: render("input.Rmd", "pdf_document") To select from the various formats defined you can pass a format name to render. Multiple formats can be specified in metadata:. If you aren't specifying format options you can also just use a simple format name:. These formats can also be specified in metadata, for example:. R Markdown has built in support for several output formats (HTML, PDF, and MS Word documents as well as Beamer presentations). For example, this metadata included at the top of an Rmd file adds a table of contents and chooses a different HTML theme:. R Markdown documents can contain a metadata section that includes both title, author, and date information as well as options for customizing output. You can also specify a plain markdown file in which case knitting will be bypassed: render("input.md") Output Formats Calling render will knit the specified input document and then produce the final output document using pandoc: render("input.Rmd") The render function is used to convert R Markdown (Rmd) files into various output formats (the default is HTML). See the pandoc installation instructions for details on installing pandoc for your platform. If you want to use the rmarkdown package outside of RStudio then you can install the package from CRAN as follows: install.packages("rmarkdown")Ī recent version of pandoc (>= 1.12.3) is also required. If you are working within RStudio then you can simply install the current release of RStudio (both the rmarkdown package and pandoc are included). See the R Markdown documentation for full details. Note that PDF output (including Beamer slides) requires an installation of TeX.
