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
```
And this is the result:
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")
```
![plot of chunk unnamed-chunk-2](figure/unnamed-chunk-2.png)
and some math.
\[ f_Z(z) = \frac{1}{\sqrt{2 \pi}} \exp \left( - \frac{z^2}{2} \right) \]
