This page is moving to a new website.

This is the github repository of Ben Baumer. He is one of the co-authors of “Modern Data Science with R” and the data and code from that book is available here. He also provides code and data for OpenWAR, an open source method for calculating a baseball statistic, Wins Above Replacement. Finally, there is an R library for extracting, transforming, and loading “medium” sized datasets into SQL. Medium here means multi-gigabyte sized files. Related to this are a couple of “medium” sized data sets from the Internet Movie Database and from the NYC CitiBike dataset. Continue reading →

PMean: Open source as a budgetary measure

This page is moving to a new website.

Like a lot of public universities, UMKC is having a lot of financial difficulty. They are asking for advice from faculty members on how to address this budget shortfall. Not being the bashful type, I suggested that we stop paying commercial software vendors and commercial journal publishers and rely instead on open source. Here’s the details of my letter.

PMean: What are the important packages for R

This page is moving to a new website.

I got a question from one of the students in my “Introduction to R” class asking what are the important packages for R. That’s a hard question to answer, but if I got only easy questions, they wouldn’t be paying me the big bucks. Here’s what I think. Continue reading →

Recommended: Analyze Survey Data for Free

This page is moving to a new website.

I’ve not had a chance to test this code, but it looks pretty good for anyone who might want to analyze one of the dozens of large databases produced by the U.S. Government. Continue reading →

PMean: It only looks like a blank

This page is moving to a new website.

I was having trouble with trailing blanks in an R program. There were some strings that looked like ” Y” and “Y ” and it’s easy enough to fix this, but one of the “Y ” values was not converting properly. The second character wasn’t a blank, but it looked like it. Here’s what I had to do. Continue reading →

Recommended: Why R is Bad for You

This page is moving to a new website.

Arguing about R versus SAS often takes on a religious fervor, so I normally hesitate to recommend articles that trash one package or the other. But this one raises an interesting point which makes it worth reading. Note that “recommended” does not mean that I endorse these conclusions. But rather than bias you with my perception of the issue, just read this on your own. Continue reading →

This page is moving to a new website.

It’s very easy, apparently, to set up your own server to run Shiny apps (Shiny is a web based method for interacting with R code). If you have set up Amazon Web Services, then it is even easier. Here is a detailed account of how to do this. Once I get my own Shiny server going, I will let you know. Continue reading →
