title: What does %>% function mean in R?
body: <p>I have seen the use of <code>%&gt;%</code> (percent greater than percent) function in some packages like <strong><a href="https://github.com/hadley/dplyr" rel="noreferrer">dplyr</a></strong> and <strong><a href="https://github.com/hadley/rvest" rel="noreferrer">rvest</a></strong>.  What does it mean? Is it a way to write closure blocks in R?</p>
