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:

`summary(cars)`

```
## speed dist
## Min. : 4.0 Min. : 2.00
## 1st Qu.:12.0 1st Qu.: 26.00
## Median :15.0 Median : 36.00
## Mean :15.4 Mean : 42.98
## 3rd Qu.:19.0 3rd Qu.: 56.00
## Max. :25.0 Max. :120.00
```

You can also embed plots, for example:

The border around the graph above is due to custom CSS for this site (see `public/css/custom.css`

). The caption was produced with some HTML:

`<p class = "figcaption">Here is a plot for you.</p>`

You can write mathematics, of course, but the syntax will be a bit different from R Mardown. Here’s some inline math: \[ \pi/2 \approx 1.57 \]. There is displayed math as well:

\[ \sum_{i=1}^{n} i = \frac{n(n+1)}{2}.\]

Here’s the source so you can see how the above worked:
