# Pipeline

## Three steps

One way is to write the presentation in R markdown (Rmd) using [Rstudio](http://www.rstudio.com/)

Then you use [knitr](http://yihui.name/knitr/) to export it to markdown.

And finally use [pandoc](http://johnmacfarlane.net/pandoc/) to create the html slides.

More [here](http://yihui.name/en/2012/05/how-to-make-html5-slides-with-knitr/) and [here](http://fellgernon.tumblr.com/post/35587597245/introduction-to-r-and-biostatistics-2012-version#.UMANV5Pjl18)

# Video

## Youtube

This is just an example of how to include youtube videos on an html presentation.

Basically in the Rmd file you add the video using _div_ and _iframe_ html tags directly:

```{r, eval=FALSE}
<div align="center">
<iframe width="560" height="315"
src="http://www.youtube.com/embed/9bZkp7q19f0"
frameborder="0" allowfullscreen>
	</iframe></div>
```

## Result

<div align="center"><iframe width="560" height="315" src="http://www.youtube.com/embed/9bZkp7q19f0" frameborder="0" allowfullscreen></iframe></div>

# Extra

## Rcode

Well, _knitr_ is really made to include R code

```{r }
summary(cars)
```

## Plots

```{r out.width="400px", out.height="400px", fig.width=5, fig.height=5, fig.align='center', dpi=300}
plot(cars, col = "blue")
```


## Math

And some equations

$$ f_Z(z) = \frac{1}{\sqrt{2 \pi}} \exp \left( - \frac{z^2}{2} \right) $$

# Steps

## Briefly

* Write the Rmd file in Rstudio
* Click on the _Knit HTML_ button
* Run the following command
```{r, eval=FALSE}
pandoc -s -S --webtex -t dzslides
filename.md -o outputName.html
```
