```

## R Markdown

This is an R Markdown document. Markdown is a simple formatting syntax for authoring HTML, PDF, and MS Word documents. For more details on using R Markdown see <http://rmarkdown.rstudio.com>.

When you click the **Knit** button a document 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 cars}
summary(cars)
```

## Including Plots

You can also embed plots, for example:

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

Note that the `echo = FALSE` parameter was added to the code chunk to prevent printing of the R code that generated the plot.

```{r}
library(ggplot2)
```

```{r, echo = FALSE, fig.cap="Two plots of random noise.", fig.show='hold', out.width="50%"}
x <- rnorm(100)
y <- runif(100)


ggplot() +
  geom_point(aes(x, y))

ggplot() +
  geom_histogram(aes(x))

```
