## 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)
```
