Dudewicz,  from/for the Short Book Reviews section of the International Statistical Review, I was obviously impressed by its size (around 1700 pages and 3 kilos…). From briefly glancing at the table of contents, and the list of standard

Today, I was amazed by how quick I conjured a map of India with the headquarters of the microfinance institutions that report data to the MIX market depicted on that map.

SIGKDD 2011 Conference — Days 2/3/4 Summary

<< My review of Day 1. I am summarizing all of the days together since each talk was short, and I was too exhausted to write a post after each day.

Quick labels within figures

One of the coolest R packages I heard about at the useR! Conference: Toby Dylan Hocking‘s directlabels package for putting labels directly next to the relevant curves or point clouds in a figure.
