Video in report
========================================================

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

Basically you use **knitr** through [Rstudio](http://www.rstudio.com/). Then you add the video using _iframe_ html tag directly:


```r
<iframe width="560" height="315" src="http://www.youtube.com/embed/9bZkp7q19f0?rel=0" frameborder="0" allowfullscreen></iframe>
```


And this is the result:

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

Well, _knitr_ is really made to include R code


```r
summary(cars)
```

```
##      speed           dist    
##  Min.   : 4.0   Min.   :  2  
##  1st Qu.:12.0   1st Qu.: 26  
##  Median :15.0   Median : 36  
##  Mean   :15.4   Mean   : 43  
##  3rd Qu.:19.0   3rd Qu.: 56  
##  Max.   :25.0   Max.   :120
```

```r
plot(cars, col = "blue")
```

and some math.

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