Packages for R are being added and updated so frequently now that it's tough to keep up with them all (the @CRANberriesFeed Twitter feed helps, though). But here are a couple of recent package updates that caught my eye:
- The Rcpp package for seamless integration between R and C++ has been updated. While most of the changes are under the hood, new users will appreciate the updated FAQ and Quick Reference Guide.
- The powerful data-wrangling packages reshape2 and plyr have had several updates recently.
- The rms package of regression tools has been updated with new capabilities for Cox regression.
- The formatR package has been updated with a new function to reformat R source code for easier reading.
