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] -1.59847 0.60567 1.43251 1.42856 -0.51736 -1.58824 -0.59153
## [8] -0.15327 1.42950 -1.38170 0.59505 1.03072 -1.36442 -0.82947
## [15] -0.81742 0.40054 1.87615 -0.03912 0.32549 0.27963
```

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