New Book in Text Analysis for R

May 11, 2017 | Ian

Focus for books on R tend to be highly focused on either statisticians or programmers.

September 13, 2016 | Ian

A new version of the OpenStreetMap package has been released to CRAN. OpenStreetMap 0.3.3 contains several minor improvements.

This is a quick note on profiling your compiled code on the mac. It is important not to guess when figuring out where the bottlenecks in your code are, and for this reason, the R manual has several suggestions on how to profile compiled code running within R. All of ... [Read more...]

Great Infographic

March 4, 2013 | Ian

This is a really great exposition on an infographic. Note that the design elements and "chart junk" serve to better connect and communicate the data to the viewer. The choice not to go with pie charts for the first set of plots is a good one. The drawbacks of polar ... [Read more...]

Climate: Misspecified

December 4, 2012 | Ian

I'm usually quite a big fan of the content syndicated on R-Bloggers (as this post is), but I came across a post yesterday that was as statistically misguided as it was provocative. In this post, entitled "The Surprisingly Weak Case for Global Warming," the author (Matt Asher) claims that the ... [Read more...]

August 20, 2012 | Ian

The book R for Dummies was released recently, and was just reviewed by Dirk Eddelbuettel in the Journal of Statistical Software. Dirk is an R luminary, creating such fantastic works as Rcpp. R for Dummies seems to have beaten Dirk's natural disinclination to like anything with "for Dummies" appended to ... [Read more...] reaches 250,000 page views and continues to grow

April 20, 2012 | Ian

It is difficult for R package authors to know how much (if at all) their packages are being used. CRAN does not calculate or make public download statistics (though this might change in the relatively near future), so authors can't tell if 10 or 10,000 people are using their work. Deducer is ...

Eclipse + Rcpp + RInside = Magic

April 8, 2012 | Ian

  I've been doing R/Java development for some time, creating packages both large and small with this tool chain. I have used Eclipse as my package development environment almost exclusively, but I didn't realize how much I relied on the IDE before I had to do some serious R/C++ ... [Read more...]

A new package OpenStreetMap has been released to CRAN this week which is designed to allow you to easily add satellite imagery, or open street maps to your plots. Raster maps are a great way to add context to your spatial data with a minimum outlay of effort. The syntax ... [Read more...]

Words in Politics: Some extensions of the word cloud

January 10, 2012 | Ian

The word cloud is a commonly used plot to visualize a speech or set of documents in a succinct way. I really like them. They can be extremely visually pleasing, and you can spend a lot of time perusing over the words gaining new insights. That said, they don't convey ... [Read more...]
