Function of the day

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

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.

Why Binning?
