## Read-And-Delete

1. Edit YAML front matter
2. Write using R Markdown
3. Use an empty line followed by three dashes to separate slides!

--- .class #id 

## Slide 2

Here is some text

```{r, results='hide'}
set.seed(42)
x <- rnorm(20)
mean(x)
var(x)
```
The first element of **x** is `r round(x[1], 3)`

## A Plot

```{r, echo=FALSE, fig.width=9.5, fig.align='center'}
par(mfcol=c(1,2))
boxplot(x)
hist(x,main='')
par(mfcol=c(1,1))
```

<q style="margin-left:140px;">The overriding design goal for Markdown’s formatting syntax is to make it as readable as possible. The idea is that a Markdown-formatted document should be publishable as-is, as plain text, without looking like it’s been marked up with tags or formatting instructions.</q>
