R Markdown

Common YAML options

# Date that automatically updates
date: "`r format(Sys.time(), '%B %d, %Y')`"

output: 
    pdf_document:
        keep_tex: TRUE # Keep the latex file
        number_sections: TRUE 

Common Setup options

Reasonable for reports

```{r setup, include=FALSE}
knitr::opts_chunk$set(
    echo = FALSE,
    cache = FALSE,
    warning = FALSE,
    message = FALSE,
    fig.align = "center",
)

# Tables
kable_standard <- function(...) {
    kable(booktabs = TRUE, linesep = "", ...) %>% 
        kable_styling(full_width = FALSE)
}

options(knitr.kable.NA = '')
```

And easily change the font size by adding this directly to the document:

<style>
body{
    font-size: 14pt;
}
</style>

Note that adding latex_options = c("hold_position") may be useful in holding tables to their current position. I wasn't able to get it to work. An alternative (but tedious) option is to add keep_tex: TRUE to the YAML (under pdf_document:) and manually add [!htbp] at the end of the \begin{figure} line in the .tex file.

Almost anything you'd want to do with a latex table can be found at:

• Create Awesome LaTeX Table with knitr::kable and kableExtra
• Create Awesome HTML Table with knitr::kable and kableExtra

Adding appendix to file

## Appendix: R Code

```{r appendix, ref.label=knitr::all_labels(),echo=TRUE,eval=FALSE}
```
