The **knitr** package (Xie 2016) is an alternative tool to Sweave based on a different design with more features. This document is not an introduction, but only serves as a placeholder to guide you to the real manuals, which are available on the package website https://yihui.name/knitr/^{1}, and remember to read the help pages of functions in this package. There is a book (Xie 2015) for this package, but it may not be useful to those who prefer digging out information on the web.

Anyway, here is a code chunk that shows you can compile vignettes with **knitr** as well using R 3.0.x, which supports non-Sweave vignettes:

```
## [1] -0.5945 0.3873 -0.1413 0.5295 1.3884 0.2908 -2.1981 0.8403 -2.1680
## [10] 0.5271 2.5546 -0.6962 -0.2223 0.1618 1.3736 1.7322 -1.3831 -0.3381
## [19] -1.7654 -0.8514
```

Estimate | Std. Error | t value | Pr(>|t|) | |
---|---|---|---|---|

(Intercept) | -17.579 | 6.7584 | -2.601 | 0.0123 |

speed | 3.932 | 0.4155 | 9.464 | 0.0000 |

The fitted regression equation is \(Y=-17.5791+3.9324x\).
