My hope is that it reduces the frustration that goes along with learning a new programming language and enhances others' ability to perform their own analysis in baseball or other sports.

In a recent post, I briefly mentioned that I may turn a majority of the focus of this blog to teaching R commands for use with sabermetric analysis. Only a few days later, Ricky Zanker began a new column at The Hardball Times doing just that. But that's okay. Hopefully both his and mine...

Joe West vs. Bruce Froemming: A Crude Umpire LHB/RHB Bias Comparison

In my last two posts, I have tinkered with the 'gam' package to create heat maps for individual umpire strike zones. I went ahead and grabbed Joe West's data (which has a lot more pitches than Bruce Froemming in it, since Froemming's data is only from...
