Package of the day

Tools for making latex tables in R

On general request, a community wiki on producing latex tables in R.

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.

Finding Data on the Internet

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.
