Mexico’s Economy
Yesterday the INEGI released the GDP figures for 2009, and since it was an annus horribilis for Mexico, I thought I'd put up a couple of charts. Looking through the Banco de Información Económica I found two series of historical seasonally adjusted GDP data available:

What to Expect?
In 2007, I was introduced to Twitter via the written qualifying exam towards my Ph.D.. At first, I did not know what to do with it. After a good year or so (maybe even sooner) passed, I began to follow some very interesting people that share the same interests as me. It has transformed my academic experience. It is...
Coming to R from SQL, Python, SAS, Matlab, or Lisp
Head over to Revolutions Blog for a list of PDF and powerpoint resources for making the transition to R from other programming or stats languages. All of these notes come from the New York R meetup.
