Thanks to gappy3000 I optimized my code in few several ways. The original script lasted ~30 minutes thanks to using pure vectors instead of zoo objects. First of all I changed all lm functions for lm.fit functions. Although lm.fit function cannot handl...
Well I totally botched my launch last week. Thankfully, my wife straightened me out: I decided to change the name of Rack to Rook so there won’t be any future confusion. And instead of rewriting all my posts last week, just read them again and every...
John Fox will be teaching a two-day introductory R workshop at McMaster University in Hamilton, Ontario, on May 24 and 25. The workshop will largely be based on materials from Fox and Weisberg, An R Companion to Applied Regression, Second Edition (Sage, 2011). Further information about the workshop is available at: https://www.socialsciences.mcmaster.ca/registrations/john-fox-introduction-to-r/fg_base_view_p3. A few spaces in the workshop are reserved for non-McMaster attendees and made...
For a project I’m working on at work, I’m building a predictive model that categorizes something (I can’t tell you what) into two bins. There is a default bin that 95% of the things belong to and a bin that the business cares a lot about, containing 5% of the things. Some readers may be
Here's a video tutorial where I walk through some code that does what the previous post describes.The FRED data is used extensively for macroeconomics. You might these data useful for joining in graph fights in the blogosphere.

So I previously took a look at some data of player performance from a computer game. In this post, I’m going to do some further visualisations using ggplot2. The data consists of different types of player character, different roles for those characters, and their overall damage output (the unit here is damage per second, or
After several months, it was time for a new release 0.2.4 of RInside which is now on CRAN. RInside is a set of convenience classes which facilitate embedding of R inside of C++ applications and programs, using the classes and functions provided by th...
