When blogging about statistics and R, it is very useful to differentiate the body text to R code. I used to manage this issue by highlighting the code and pretty-R was a valuable instrument from Revolutions Analytics to accomplish this. However, as you may know, Microsoft acquired that company, and now this feature (dressing R code for the web) is not available anymore.
After some searching, I found this online syntax highlighter and it seems to work pretty well. Besides, it allows you to select from different styles, and you can even choose among a lot of computational languages.
