Markdown is a simple formatting syntax for authoring web pages (click the **MD** toolbar button for help on Markdown).

When you click the **Knit HTML** button a web page will be generated that includes both content as well as the output of any embedded R code chunks within the document. You can embed an R code chunk like this:

```{r}
library(ggmap)
map.center <- geocode("Kevin Street, Dublin")
DITmap <- qmap(c(lon=map.center$lon, lat=map.center$lat), source="google", zoom=15)
```
```{r}
summary(cars)
```

You can also embed plots, for example:

```{r fig.width=7, fig.height=6}
plot(cars)
```
```{r fig.width=7, fig.height=6}
DITmap + geom_point(y = 53.337089, x = -6.268484, size = 10, color = "blue")
```
