- YAML current date in rmarkdown 3 answers

I am using R Markdown to produce a Beamer presentation. How can I put the date that authomatically updates his values? The current setting are below:

```
title: "MyTitle"
author: "MyName"
date: "19th April 2015"
output:
beamer_presentation:
incremental: no
keep_tex: yes
toc: yes
ioslides_presentation:
incremental: yes
header-includes:
- \usepackage{url}
bibliography: myBib.bib
```

Answer:

Just use `\today`

, I think it should work but only if your output is PDF (which uses LaTeX) or a Beamer presentation.
