Overcoming D3 Cartographic Envy With R + ggplot

When I used one of the Scotland TopoJSON files for a recent post, it really hit me just how much D3 cartography envy I had/have as an R user. Don’t get me wrong, I can conjure up D3 maps pretty well and the utility of an interactive map visualization goes without saying, but

Regular expressions for everyone else

Regular expressions are an amazing tool for working with character data, but they are also painful to read and write.  Even after years of working with them, I struggle to remember the syntax for negative lookahead, or which way round the start and end anchor symbols go. Consequently, I’ve created the regex package for human

Estimating Generalization Error with the PRESS statistic

As we’ve mentioned on previous occasions, one of the defining characteristics of data science is the emphasis on the availability of “large” data sets, which we define as “enough data that statistical efficiency is not a concern” (note that a “large” data set need not be “big data,” however you choose to define it).
