an example for yihui/knitr#547
changes in the highlight package
syntax highlighting is done via highr now
update cache for 009, 010
use kable() instead of xtable, and no 'tiny' argument
the row names 1:n are hidden by default in kable()
use .TEX for the gb2312 example, so that `make pdf` will exclude it
it is hard to know which tex file is problematic with xargs -P4, so replace it with a plain loop
make clean also cleans cache files; improved the regexp for grep
use quiet=TRUE for knit() instead of progress=FALSE, and redirect output to null device
use include=FALSE instead of two options
knitr does not use highlight any more
the highlight theme does not work here
use a more striking theme
the highlight engine was improved; the theme is consistent across all chunks now
flowchart example
smaller code width
need to rm() everything before running a single example; reported to hadley/ggplot2#837
run knit() quietly
an example of saving the chunk to a file
