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.org/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] 1.545004 1.131897 0.002776 -0.082819 2.409905 -1.396916 1.083896
## [8] 1.802385 0.627644 -1.241974 -1.485010 -0.979978 -0.378730 0.190003
## [15] 1.241976 -0.617919 1.056736 0.418370 -0.569578 0.858991
```

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 \(Y=-17.5791+3.9324x\).
