We will cover the following tasks in 34 minutes:
In this section we will discuss the dplyr cheat sheet on RStudio’s website. We will talk about course objectives. We will then go over the Virtual Machine and I will tell you a little about myself.
The Select function is your friend. You will learn how to quickly slice your data frames to create new ones using this function.
It’s time to dice. Do you want to quickly know which rows meet a certain criteria? This is your function. Join me and we will go over it.
This is not plumbing. Nope. The pipe is the glue that keeps the dplyr verbs together. Use this for neat and efficient code.
Oh you want to arrange your data in descending order. Look no further than arrange. I will walk you through this bad boy.
This is my favorite. Think pivot table in Excel on Steroids. I’ll walk you through its magic. By the way, this lesson is a two’fer since I throw in group_by as well. Join me and I’ll show you all about this wicked great verb combo.
Last but not least, mutate will help you create new variables – and much quicker than base R ways.
