A reST document for knitr
=========================

This is a reStructuredText document. The input filename extension is ``Rrst``
and the output filename will be ``rst``. Here is how we write R code in
**knitr**:

.. {r setup}
options(width = 75)
library(knitr)
# do not use the sourcecode directive
render_rst(strict=TRUE)

# global chunk options
opts_chunk$set(fig.width=5, fig.height=5)
.. ..

More examples
-------------

A code chunk begins with ``.. {r label, options}``, and ends with ``.. ..``
(note the space in between). Optionally you can precede all R code with two
dots, e.g.

.. {r rst-example}
.. 1+1
.. set.seed(123); rnorm(10)
.. warning('do not forget the space after ..!')
.. ..

Here is a plot:

.. {r rst-plot, out.width='360px', fig.cap='A ggplot2 example', message=FALSE, warning=FALSE}
library(ggplot2)
qplot(hp, mpg, data=mtcars) + geom_smooth()
.. ..

Inline R code is like this: the value of pi is :r:`pi`.
