title: How to remove first N rows in a data set in R?
body: <p>I saw this <a href="https://stackoverflow.com/questions/21148498/remove-last-n-rows-in-data-frame-with-the-arbitrary-number-of-rows">stack-overflow question</a> already. But what I want is to remove first N rows in my data set. I can't think of a solution as I am new to R.</p>
