Most of the data on the web is in large scale as HTML. It is often not available in a form that is useful for analysis, such as hierarchical or tree-based:
<html>
<head>
<title>Looks like a tittle</title>
</head>
<body>
<p align="center">What's up ?</p>
</body>
</html>
rvest is a very useful R library that helps you collect information from web pages. It is designed to work with magrittr, inspired by libraries such as BeatifulSoup.
