 Except the GFM demo, you can directly use `knit()` to knit the input file, e.g.,
 
 {% highlight r %}
 library(knitr)
 knit('knitr-minimal.Rnw')
-knit('knitr-minimal_knit_.html')
+knit('knitr-minimal.Rhtml')
 {% endhighlight %}
 
 The instructions on how to knit the GFM demo are in the md file. Note for the HTML demo, you need to install the **rgl** package to get the snapshot in the output.
