Function of the day

Construct the path to a file from components in a platform-independent way.

Package of the day

This package implements a data structure similar to hashes in Perl and dictionaries in Python but with a purposefully R flavor. For objects of appreciable size, access using hashes outperforms native named lists and vectors.

Question of the day

On general request, a community wiki on producing latex tables in R. In this post I'll give an overview of the most commonly used packages and blogs with code for producing latex tables from less straight-forward objects. Please feel free to add any I missed, and/or give tips, hints and little tricks on how to produce nicely formatted latex tables with R.

The 14th annual KDnuggets poll measuring use of analytics software is open for voting. The poll asks, "What Predictive Analytics, Big Data, Data mining, Data Science software you used in the past 12 months for a real project?" and allows up to 20 choices from commercial software, open source software, and "big data" software.

I'm very proud to have been selected today for Big Data Republic's list of the Top 20 Big Data Twitter accounts. With such Big Data practitioners, analysts and thought leaders like Kirk Borne, Hilary Mason, Pete Skomoroch, Mike Olson and Doug Henshchen on the list, I'm humbled to be listed at #3.

What I would like is a nice list of all of credible sources on the Internet for finding data to use with R projects. I know that this is a crazy idea, not well formulated (what are data after all) and loaded with absurd computational and theoretical challenges. (Why can't I just google "data R" and get what I want?) So, what can I do? As many people are also out there doing, I can begin to make lists (in many cases lists of lists) on a platform that is stable enough to survive and grow, and perhaps encourage others to help with the effort.
