Dplyr Tutorial

Deepanshu Bhalla has a nice dplyr tutorial:

What is dplyr?
dplyr is a powerful R-package to manipulate, clean and summarize unstructured data. In short, it makes data exploration and data manipulation easy and fast in R.
 
What’s special about dplyr?

The package “dplyr” comprises many functions that perform mostly used data manipulation operations such as applying filter, selecting specific columns, sorting data, adding or deleting columns and aggregating data. Another most important advantage of this package is that it’s very easy to learn and use dplyr functions. Also easy to recall these functions. For example, filter() is used to filter rows.

dplyr is a core package when it comes to data cleansing in R, and the more of it you can internalize, the faster you’ll move in that language.
