## R Markdown

This is an R Markdown document.
It is a script written in markdown with the possibility to insert chunk of R code in it.
To insert R code, it needs to be encapsulated into inverted quote.

Like that for a long piece of code:

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

And like ``r cat("that")`` for small piece of code.

## Including Plots

You can also embed plots, for example:

```{r echo=FALSE}
`plot(pressure)`
```
