Adding a block of R code is easy. When this document is knit, the default is to print the code and the output - for example:

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

Although, you can also add "echo=FALSE" to the "```{r echo=FALSE}" and the code will not print, but the outputs will still be shown:

```{r echo=FALSE}
summary(cars)
```

You can also embed plots using the same method, for example:

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