R Help tooltips

March 24, 2013

I created a simple jquery plugin to display some information when hovering links to r documentation files hosted at help.r-enthusiasts.com

Below is a snapshot from highlight.r-enthusiasts.com that uses the tooltips:

See also a live example here: data.frame

Using this feature is simple. You just need to include jquery and my plugin like this:

<link rel='stylesheet' href='//highlight.r-enthusiasts.com/css/highlight.css'>
<script src="//highlight.r-enthusiasts.com/js/highlight.js"></script>

And that’s it, all links similar to

<a href="http://help.r-enthusiasts.com/library/base/html/data.frame.html">data.frame</a>

will get a nice tooltip showing extra information.
