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.

If you have an iPhone, you've probably noticed the new(ish) autocomplete feature: when entering text, iOS8 gives you three choices for a possible next word in the sentence. (And yes, if you have an Android phone you've had this feature for like, ever.) If you keep on pressing the middle button you'll get a sentence that is syntactically correct but largely content-free.
