Here are the presentation slides I used for my talk on “Using R for Data Mining Competitions” at Ryerson University as part of the Greater Toronto Area (GTA) R User’s Meetup Group. Presentation (Prezi) Presentation (PDF) Meetup Event page Special thanks to Anthony Goldbloom from Kaggle and various competition winners for sharing their code and
For whatever reason, Apple decided not to include OpenMPI in Mac OS X Lion (it was supported in Leopard and Snow Leopard). I found this out the hard way after doing a clean install of Lion. Here are steps to install OpenMPI and get it working with the Rmpi package in R. One benefit of
The built-in script editor for the Mac OS X R GUI actually isn’t bad. In fact it is much better than its Window’s counterpart. In particular, it has: Syntax highlighting Auto-completion Bracket matching Auto-indent Block code execution (with blocked command history) However, when coding in R and pretty much any other language, Vim has always
iPhone users who have jailbroken their phone have been able to compile R for a while now since they have access to the command line via MobileTerminal. However, I just recently found out that a package is now up on Cydia to ease installation. So I fired up my iPhone 4 and installed R on
In my last post about installing the rgdal R package on Mac OS X, I had apparently glossed over the last step of compiling the R package from source. I hadn’t realized that Mac OS X actually doesn’t come default with the necessary software to do this. Most times, prepackaged binaries work fine but occasionally,
The rgdal package contains bindings from R to the GDAL (Geospatial Data Abstraction Library) as well as the PROJ library. It is a dependency for numerous spatial statistics packages. Note that the binaries on the rgdal homepage are outdated — the most up-to-date version of the rgdal package can be found on CRAN. Unsurprisingly, rgdal
Throughout the course of my research, I come across a lot of obstacles and nuisances that are either undocumented or documented poorly. Therefore, I decided to throw up this blog as a repository of sorts to store all of these little tidbits of information with the hope that it will save somebody somewhere a few minutes of
Zero Inflated Models and Generalized Linear Mixed Models with R.
