In our book, Max and I describe the process of downloading Retrosheet play-by-play data (Appendix A.1) and computing run values of all events (Chapter 5). Here we illustrate some updated functions for downloading the data and computing the run values.

Downloading the Data
Our book assumes that you have a Windows environment, but now I use a Mac laptop and so I was motivated to adapt our downloading instructions for a Mac.

1. If you have a Mac, you need to install the Chadwick files. Here is an excellent description of how to install the Chadwick Software on a Mac.

2. In the current working directory, create a “download.folder”, and two subfolders “unzipped” and “zipped” inside “download.folder”. From the book script and data web site, download the file fields.csv and put this file in the “upzipped” folder. (For a Windows computer, you need to have the Chadwick cwevent.exe inside the “upzipped” folder.)

3. I updated a function parse.retrosheet2.pbp (a slight modification of the one provided in our book) that downloads the Retrosheet play-by-play and roster files for a particular season and uses the Chadwick program to extract the data and creates two data files. What’s new is that the function will work for both Mac and Windows. You can see the function here — you can read this function into R by typing …

Computing Runs Values
1. In Chapter 5, I describe how to compute the run values for all plays. I have put all of the R code into a new function compute.runs.expectancy which is found here and can be sourced into R:

2. Now we’re ready to download, say all of the 2013 season play-by-play data, and compute the runs values.

3. The data frame d2013 contains all of the 2013 play data. I wrote a short function runs.expectancy to compute the expected runs in the remainder of the inning for all 24 bases/outs situation.

The 2013 expected runs are similar to those found from 2011 season data in Chapter 5 of the book. In the next post, I’ll use this play data frame to see which players last season were best in performing in the clutch.

Retrosheet Software Tools for Event Files

The first three program files are 'zipped.' Most likely you already have software to 'unzip' (i.e. extract files from a .zip archive) these files. For example, it is built into Windows XP and later versions of Windows. If you do not have this capability, download PKUNZIP.EXE, the fourth program listed below.

All of these programs require PC DOS to run. Swords and sandals 3 full version download mac. If using Windows, you will have to open a DOS window to get a command prompt. Macintosh users may be able to run these programs using Windows or DOS emulation software. Another way for Mac users is described below.

BEVENT.EXE: Creates play-by-play data file suitable for import into database programs, spreadsheets, and custom written programs. Enter the DOS command 'bevent -h' for more information. [version update: 12/19/2020]
BOX.EXE: Generates traditional box scores from Retrosheet data files. Enter the DOS command 'box -h' for more information. [version update: 03/04/2020]
BGAME.EXE: Makes a summary of constant items for each game such as date, day or night, and the score. Enter the DOS command 'bgame -h' for more information. [version update: 09/13/2019]
PKUNZIP.EXE: Expands compressed data files from the '.zip' file archive. The DOS command 'pkunzip name.zip' will write all the files in the archive name.zip to your hard disk. The DOS command 'pkunzip 1967al.zip *.ev*' will extract only the Retrosheet event files (game data) from the archive 1967al.zip and write them on your hard drive. Enter the DOS command 'pkunzip -h' for a list of the command options. [last update: 2/1/93]

A Macintosh user has let us know how he can get these programs to run. If you have questions about this approach, you can e-mail him atmesamb1--insert the AT sign--gmail.com.

To run the Retrosheet programs Mac users will need to install Wine onto their computer. Wine will allow for the mac user to emulatea windows environment on their computer in order to run the Retrosheet programs.

First, you will need to install WineBottler. WineBottler lets you run .exe on yourMac, but we will not be using that feature for Retrosheet. Instead when you install WineBottler, you will also install the app calledWine in an easy to use package. To install WineBottler, go to the website and follow the download instructions provided.

These instructions, at the time of my writing, involve downloading the WineBottler dmg, opening the dmg which will mount a removabledrive, and then dragging the app Wine and WineBottler into your applications folder.

Once you have installed Wine and WineBottler from the WineBottler package to your application folder, you need to hold down controlon your keyboard and click on 'Wine' in your application folder. Choose 'Open' from the drop down list. You may need to enter youradministrator name and password, then when prompted select open. This is because this is an application not listed on the Apple Appstore, and your Mac OS security settings by default will not allow for the application to be opened. For more information please referto Apple support.

Once you have opened Wine, there WILL NOT be an application on your dock. Instead, on the menu bar that goes across the top of yourscreen, there will be a glass of wine icon. Click on this icon and select 'DOS Prompt' from the options.

Wine creates by default a fake windows environment on your Mac. By default the folder Wine uses as a C drive is located under: Macintosh HDUsers'Your Admin Username'Wine Filesdrive_c

The Wine DOS Prompt will allow you to navigate inside of this folder using normal DOS commands. This includes being able to run theprograms bevent.exe, box.exe, and bgame.exe

The Retrosheet software will need to be placed inside of the drive_c folder in order for them to be accessed by Wine. For example,to follow the step by step guide from here you would need to create your folder retro inside the 'drive_c' folder(which you locatedearlier) to match the step by step guides creation of a folder 'C:retro'. In Wine, a folder located as 'drive_c'->'retro' will belisted as 'C:retro'. A new folder can either be created by using Mac's Finder, or using the 'mkdir retro' command at a DOS Prompt.

Once you have expanded the Retrosheet software somewhere in drive_c you will need to move to the working directory in the manner aslisted in step 4 of the step by step guide.

From here on out, using the Wine Command Prompt is identical to using the DOS Command Prompt as explained in the Retrosheet step bystep guide.
