Data Analysis with R: Case Study with Real Data Using dplyr

This is a case study that allows you a glimpse into the life of a Data Analyst. The project isn’t glamorous, there are no machine learning algorithms but it reflects what a Data Analyst does most of the time. The tools we learned in the previous chapter along with some new one’s will help us prepare the analysis for an RMarkdown or Shiny App Presentation.

Task List


We will cover the following tasks in 44 minutes:


Introduction

In this section we’re going to look at the Big Picture. What are we going to do to the data and why.


Colnames

Sometimes Data doesn’t come in with Colnames as is the case with this Data. We will add the colnames. Just follow me along.


More Clean Up

We’re going to discuss how to change the class of a Vector. This is important. I also will show you a quick way to look at the data to see what is needed to be changed.


Funny Data

Funny data isn’t funny if you don’t catch it. It can spell trouble down the road when others are looking at your work. Come in and we’ll learn some of the more basic ways to check for funny data.


Stripping Out Data

In this chapter we’re going to remove data the old fashion way using Base R. Come in and see how to do this and also to keep up with the lesson.


Lubridate

Finally. I told you in Chapter 2 we would do Lubridate. Better than late than ever. I’ll show you a couple useful functions within the package.


Adding a Column

In this chapter I will show you how to add a column to your data set. You can also use this for feature engineering when building models down the road.


Tables and Branches

We’re going to do some analysis using our old dplyr tool set. We’re going to group by Branch and then do some analysis to see which branches are not living up to the others.


More Analytics

Let’s dive in a little further and see how the Credit Department might freak out at some of these orders.

Frequently Asked Questions


In Rhyme, all projects are completely hands-on. You don't just passively watch someone else. You use the software directly while following the host's (Rhyme Authors) instructions. Using the software is the only way to achieve mastery. With the "Live Guide" option, you can ask for help and get immediate response.
Nothing! Just join through your web browser. Your host (Rhyme Authors) has already installed all required software and configured all data.

Absolutely. We offer Rhyme for workgroups as well larger departments and companies. Universities, academies, and bootcamps can also buy Rhyme for their settings. You can select projects and trainings that are mission critical for you and, as well, author your own that reflect your own needs and tech environments. Please email us at help@rhyme.com
Rhyme strives to ensure that visual instructions are helpful for reading impairments. The Rhyme interface has features like resolution and zoom that will be helpful for visual impairments. And, we are currently developing a close-caption functionality to help with hearing impairments. Most of the accessibility options of the cloud desktop's operating system or the specific application can also be used in Rhyme. If you have questions related to accessibility, please email us at accessibility@rhyme.com
We started with windows and linux cloud desktops because they have the most flexibility in teaching any software (desktop or web). However, web applications like Salesforce can run directly through a virtual browser. And, others like Jupyter and RStudio can run on containers and be accessed by virtual browsers. We are currently working on such features where such web applications won't need to run through cloud desktops. But, the rest of the Rhyme learning, authoring, and monitoring interfaces will remain the same.
Please email us at help@rhyme.com and we'll respond to you within one business day.
