About This Course

Published 9/2015 English

Course Description

This course is about working with large sets of PITCHf/x data to create batting location charts. We use R to scrape and visualize the data and MySQL to store the data. The course includes lessons on how to install a virtual Ubuntu machine, how to install MySQL, how to perform basic MySQL administrative tasks, and how to connect R and MySQL.

It would be best if you have some knowledge of R and ggplot. This can be obtained through my previous three courses in baseball analytics. However, it might be possible to follow along without this.

At a relaxed pace, the course should take about two weeks to complete.

What are the requirements?

  • Students should have R and RStudio installed.
  • Students should also have VirtualBox and Vagrant installed.
  • It would be best if students have gone through my previous three courses in baseball analytics. This may not, however, be completely necessary.

What am I going to get from this course?

  • install MySQL on a Ubuntu machine.
  • perform basic administrative tasks in MySQL.
  • use the vi program to edit the MySQL configuration file.
  • perform port-forwarding with Vagrant.
  • scrape hit location data from PITCHf/x.
  • query MySQL from R.

What is the target audience?

  • This course is for those who want to learn how to create a hit location chart from PITCHf/x data.
  • The course is also for those who wish to know a little about working with R and MySQL together.
  • The course is NOT for complete beginners in R.

Curriculum

Section 1: Setting up MySQL
01:03

In this lecture, I briefly discuss how the course will unfold.

01:49

This is a review of the process of installing an Ubuntu virtual machine.

02:39

After viewing this lecture, you will be able to install MySQL.

01:13

After viewing this lecture, you will be able to login and logout of MySQL.

06:41

After viewing this lecture, you will be able to create a user in MySQL.

02:12

After viewing this video, you will be able to grant user privileges in MySQL.

05:26

After viewing this lecture, you will be able to use the vi program to edit the MySQL configuration file to allow MySQL to accept requests from all IP addresses.

05:12

After viewing this lecture, you will be able to forward ports via Vagrant.

Section 2: Visualization with R
01:56

In this lesson, I show you how to load the packages you will need to visualize the hit locations in R.

05:32

After viewing this lecture, you will be able to scrape hit location data from PITCHf/x.

02:18

In this lecture, we get acquainted with the data we have stored in MySQL.

02:42

In this lecture, we decide what information we want to extract from our database into R.

01:45

After viewing this lecture, you will be able to query a MySQL database from R.

05:40

In this lecture, we modify the data we extracted from MySQL to make our visualization task easier.

03:56

In this lecture, we build the foundation of our plot, visualizing only the locations of where the hits were fielded.

06:48

In this lecture, we enhance the plot by indicating whether each batted baseball was a home run, single, double, or a non-hit. We do this by utilizing the color, shape, and size parameters.

03:09

After viewing this lecture, you will be able to delete a MySQL database. We will also scrape a season's worth of PITCHf/x data and store it in MySQL.

05:18

In this lecture we put everything together and apply what we've learned to a larger data set.
