I searched for a javascript plugin to highlighter code, but obviously not any code. I needed to higlight R. Finally I founded highlight.js. Highlights.js is pretty cool for many reasons. I like Highlights.js because:

1. Support R lenguage.
2. It’s easy to use. Works automatically. That’s mean you don’t have to put the code what are you writing. Highloght it does alone.
3. A lot of styles.
4. And yep! Again! Support R lenguage.

function(x, inf = -Inf, sup = Inf){
  if(missing(inf)) return(ifelse(x < sup, x, sup))
  if(missing(sup)) return(ifelse(x > inf, x, inf))
  x <- ifelse(x < sup, x ,sup)
  x <- ifelse(x > inf, x ,inf)
  return(x)
}

And an example of python code:

class RandomPostView(View):

    template_name = "blog/post.html"

    def get(self, request, *args, **kwargs):
        post = Post.objects.filter(status = 1).order_by('?')[0]
        return HttpResponse('Hello, World!')

Nice!
