```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = TRUE)
```

## Asking the maths library
My computer tells me that $\pi$ is approximatively


```{r cars}
pi()
```

It is also straightforward to include figures. For example:

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

Note the parameter `echo = FALSE` that indicates that the code will not appear in the final version of the document. We recommend not to use this parameter in the context of this MOOC, because we want your data analyses to be perfectly transparent and reproducible.

Since the results are not stored in Rmd files, you should generate an HTML or PDF version of your exercises and commit them. Otherwise reading and checking your analysis will be difficult for anyone else but you.

Now it's your turn! You can delete all this information and replace it by your computational document.
