13.4 LaTeX content

As the only output format of the rticles formats is PDF, the content of the documents may include raw LaTeX formatting. This means you may use LaTeX to produce figures and tables (if you have to), e.g.,

\caption{An example image.}

Unless you have specific requirements for using LaTeX, we recommend that you use the R Markdown syntax. This keeps you work generally more readable (in terms of the source document), and less prone to formatting errors. For example, the above code block would be better represented as:

```{r foo, out.width="100%", fig.cap="An example image."}
