Introduce your friends to R
R has gotten quite a lot of exposure recently. It started with the feature article in the New York Times last January, but since then there's been a steady flow of articles about R in analyst reports, on blogs, in YouTube videos, on Twitter, as well as in the general news media. As a result, a lot of new...
New features in ggplot2 version 0.85
Hadley Wickham recently updated the ggplot2 package for R to version 0.8.5. In addition to bugfixes and performance improvements, this version introduces some handy new features. Among them: the ability to display mathematical equations as text, automatic legends for color scales, and user-configurable axis labels and legend titles. The Learning R blog runs through the new features with worked...
A tale of two visualizations (because it’s Friday)
GEEK FIGHT!!! says JD Long on Twitter as the New York Times publishes a widely-reposted interactive graphic about Netflix rental data, and the Wall Street Journal also gets into the interactive-viz game with a graphic on bank bonuses. If it's a fight, it's a knockout in the first round, if you ask me. There's no surprise why the Netflix...
Equivalents to SAS, SPSS modules in R
Bob Muenchen, the author of R for SAS and SPSS Users, has created a handy table listing the R packages that implement the statistical methods included in add-on modules for SAS and SPSS. For example, if you're looking for the equivalent structural equation modeling functions you might be using in PROC CALIS from SAS/STAT or the SPSS "Amos" software,...
Coming to R from SQL, Python, SAS, Matlab, or Lisp
The theme of last week's meetup of the New York R User Group was The R Rosetta Stone and focused on translating between R and other data languages: SAS, Matlab, SQL, Python and Clojure. I really wish I'd been there, because it's a great topic -- one of the best ways to get started with R is to bootstrap...
Quick thoughts on “R-Powered Web Apps”
Good session at last nights Bay Area UseR Group meeting on R-Powered Web Apps. First of all, there's clearly a lot of interest in using R in Web-based applications: although the program was only announced a week ago, more than 100 people showed up for the talks from Jeff Horner and Jeroen Oons. Second, the Twitter offices are very...
In case you missed it: December roundup
In case you missed them, here are some articles from last month of particular interest to R users. This post looked at a climate change controversy involving the weather in Darwin, Australia and a review of the source data using R. This post showed how to access global weather data from the US National Centers for Environment Prediction using...
