In this post I offer an alternative function for boxplot, which will enable you to label outlier observations while handling complex uses of boxplot.

sab-R-metrics: Intermediate Scatter Plots
First off, I'll say it's been a whirlwind of a past few days. Thanks to David Smith at the Revolutions Blog for his kind words about the sab-R-metrics series and link back this way. Add in Ed Kupfer's posts at the APBRmetrics board, Harry Pavlidis at THT, Dave Allen at Fangraphs...

The Art of Exploratory Data Analysis
This blog is about the art of exploratory data analysis, which is also the subject of my new book, Exploring Data in Engineering, the Sciences, and Medicine (http://www.oup.com/us/ExploringData). This art is appropriate in situations where y...
Hard drive occupation prediction with R – part 2 – Getting the probability distribution
On the first article, we saw a quick-and-dirty method to predict disk space exhaustion when the usage pattern is rigorously linear. We did that by importing our data into R and making a linear regression. In this article we will see the problems wit...

Learning R through baseball: sab-R-metrics
The words "statistics" and "baseball" are often found near each other, but there's a lot more to statistics than dividing the number of hits by the number of swings to get a batting average. And there's a lot more to sabermetrics -- the statistical analysis of baseball -- than averages, too. Many baseball fans are also stats geeks (and...
sab-R-metrics: Intermediate Boxplots and Histograms
Last week, I began talking about using the base graphics in R. Those graphics were pretty bland, and my hope for the next two posts is to introduce some interesting additions to the basic graphics that come from R: color, legends, lines, shapes, multiple graphs side-by-side, text, point types, and custom axes. If you have missed...

sab-R-metrics: Beginning with Boxplots, Scatterplots, and Histograms
Today I decided to begin more with visualizations and less with basic statistical analysis for sabermetrics using R. I'm not really here to teach the ins and outs of regressions and statistical tests, so once I get there, I'm hoping that those who have read this already have a decent understanding of those subjects before implementing them. ...
