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.

Pearl Jam has been featuring in my playlist recently, which reminded me of this old Misheard Lyrics video for Yellow Ledbetter:   The funny think is, I don't think Yellow Ledbetter has official lyrics, so these might be as good as any. I've seen it performed a few times on stage, and each time the lyrics are different. Not as wildly divergent as these, but still: variations each time. (If anyone does know what the actual lyrics are, please point me to the source!) That's all for this week. See you Monday!
