A bit _introduction_ here.

# Start with a cool section

You can use traditional **Markdown** syntax, such as [links](http://yihui.org/knitr) and `code`.

# Followed by another section

Of course you can write lists:

- apple
- pear
- banana

Or ordered lists:

1. items
1. will
1. be
1. ordered
    - nested
    - items

# More sections

## Hi

hi hi

## Hello

hello hello

## Howdy

howdy howdy

# Okay, some R code

```{r linear-model}
fit = lm(dist ~ speed, data = cars)
b = coef(fit)  # coefficients
summary(fit)
```

The code will be highlighted in all output formats.

# And some pictures

```{r lm-vis, fig.cap='Regression diagnostics'}
par(mfrow = c(2, 2), pch = 20, mar = c(4, 4, 2, .1), bg = 'white')
plot(fit)
```

# A little bit math

Our regression equation is $Y=`r b[1]`+`r b[2]`x$, and the model is:

$$ Y = \beta_0 + \beta_1 x + \epsilon$$

# Pandoc extension: definition lists

Programmer
:   A programmer is the one who turns coffee into code.
LaTeX
:   A simple tool which is nothing but a couple of backslashes.

# Pandoc extension: examples

We have some examples.

(@) Think what is `0.3 + 0.4 - 0.7`. Zero. Easy.
(@weird) Now think what is `0.3 - 0.7 + 0.4`. Still zero?

People are often surprised by (@weird).

# Wowzaaaaa

```{r}
#| my-chunk, echo = FALSE, fig.width = 10,
#| fig.cap = "This is a long long
#|   long long caption."

plot(cars)
```

# Pandoc extension: tables

A table here.

Table:  Demonstration of simple table syntax.

  Right     Left     Center     Default
-------     ------ ----------   -------
     12     12        12            12
    123     123       123          123
      1     1          1             1

# Pandoc extension: footnotes

We can also write footnotes[^1].

[^1]: hi, I'm a footnote

Or write some inline footnotes^[as you can see here].

# Pandoc extension: citations

We compile the R Markdown file to Markdown through **knitr**. For more about @xie2013, see <http://yihui.org/knitr>.
